At noon on 12 October NEA's 24-hour PSI read 146 in the central region and 147 in the west, a day after peaking at 152, the worst reading of this haze season. We re-checked all eight brands on their own Singapore stores the same day, and stock is now the story, not price. Every Sharp air purifier shows out of stock, novita has sold out of the A5i, A11i and A18i, and EuropAce's $139 and $199 HEPA-14 models have become pre-orders with earliest delivery on 11 November. What you can still get delivered: Tefal's Pure Air Mini at $99.90 (back in stock), Mistral's MBFAP250 tower at $159 and MBFAP460 at $289, Sterra's new Halo at $249 and its three-Moon bundle at $458, Dyson's TP10 at $599 or $549 with code PEAK50, and Coway's serviced Noble AP from $1,588.
Singapore's 24-hour PSI hit 152 on 11 October, the worst reading of this haze season, and the shelves have emptied with it.
> Quick view: Cheapest machine you can get delivered now is Tefal's Pure Air Mini at $99.90. EuropAce's HEPA-14 pair ($139 and $199) ship from 11 November. The catch: every Sharp purifier and novita's A5i, A11i and A18i are sold out. Re-checked 12 October on each brand's own store.
PRICE: the EPU1200F at $139 (U.P. $299) and the EPU3380E at $199 (U.P. $459) are still the cheapest HEPA-14 machines in this guide. Both use an H14 filter rated to capture up to 99.995% of particles down to 0.3 microns, a DC motor and a filter-change reminder. The EPU1200F moves 200m³/h, enough for a typical HDB bedroom with the door shut; the EPU3380E moves 338m³/h and is rated by EuropAce for up to 700 sq ft, so it is the one for a living room.STOCK NOW: both went on sale on 13 September and were in stock on 27 September. On 12 October EuropAce lists both as pre-orders, with earliest delivery on Wednesday 11 November 2026, so you are buying for the tail of this haze season rather than this week.FILTERS: EuropAce now lists the replacements, $49.90 for the EPU1200F pack (in stock) and $79.90 for the EPU3380E pack (pre-order). Add those to the running cost before you compare either machine with one you can have tomorrow.ALSO FROM EUROPACE: the PLAY Series EPU3320C at $199, with its Bluetooth speaker and wireless charging pad, is now sold out in both colours, and the $129 Compact EPU1110B is still delisted.BEST FOR: anyone who can wait four weeks and wants HEPA-14 at the lowest price here.
Pre-order (12 Oct), earliest delivery 11 Nov: EPU1200F $139 (U.P. $299), HEPA-14, 200m³/h · EPU3380E $199 (U.P. $459), HEPA-14, 338m³/h. Filters $49.90 / $79.90. PLAY Series sold out.
STOCK NOW: on 12 October Sharp's own Singapore store shows every one of its air purifiers out of stock: the 23m² FP-J30E at $149 (U.P. $214), the 38m² KI-N50E-H humidifying purifier at $559 (U.P. $1,063), the 84m² FX-S120E-H at $799 (U.P. $1,595), the 62m² Purefit FX-S82E at $699, the Purefit Mini FP-S42E-L at $349, and the AIoT FP-J50E-H and FP-J80E-H. Prices are unchanged, the Mid Autumn Sale listings are still up, and Sharp has restocked the FP-J30E before, so this reads as a sell-out rather than a withdrawal.STILL IN STOCK: the 30L 4-in-1 dehumidifier, air purifier, shoe dryer and laundry dryer (DW-T30FE) at $649 (U.P. $799), down to its last unit on this check. It is a dehumidifier first, but it does run a purifier stage.WHY IT STAYS: when Sharp restocks, the FX-S120E-H is still the only machine in this guide rated for a full 84m² living room, and the KI-N50E-H was the best mid-size value once you count the humidifier. Plasmacluster, Sharp's ion technology, also works on smoke smell that has settled into curtains and sofas, which is the part people notice during haze.BEST FOR: a stock alert on the FX-S120E-H if you have a large open-plan living room.
ALL air purifiers SOLD OUT on Sharp's own store (12 Oct), prices unchanged: FP-J30E $149 · KI-N50E-H $559 · FX-S120E-H $799. Still in stock: 30L 4-in-1 dehumidifier-purifier DW-T30FE $649 (U.P. $799), last unit.
STOCK NOW: Tefal's own Singapore store has swapped which model you can buy. The smaller Pure Air Mini PT1520 is back in stock at $99.90 (U.P. $180) after being sold out on our September checks, which makes it the cheapest machine in this guide you can actually have delivered this week. The two-unit PT1520 bundle at $179 is sold out. Tefal does not publish an airflow figure for the Mini on its store, so treat it as a single small bedroom or study machine rather than a living-room one.THE COMPACT: the Pure Air Compact PT2220 is still sold out at $149 (U.P. $249), as it has been since 12 September. It has now flipped four times since August, so Tefal restocks it rather than retiring it, and it is worth a stock alert. What you would be waiting for is a well-specified bedroom machine: 198m³/h CADR, three-layer filtration with a dedicated Allergy+ layer and activated carbon, three automatic modes, and 2.3kg, light enough to carry between rooms.FILTERS: Tefal's sit at the higher end of this guide's $39 to about $99 a year band, so price one before you buy.BEST FOR: a small room, today, for under $100.
Back in stock (12 Oct): Pure Air Mini PT1520 $99.90 (U.P. $180). Pure Air Compact PT2220 still SOLD OUT at $149 (U.P. $249). 2-unit PT1520 bundle $179 sold out.
PRICE: Mayer cut this unit to $309 on 27 August and to $259 on 27 September, and on 12 October it is back up $30 to $289 against a $599 list price, in stock.WHAT IT IS: a 46-inch blade-free tower sold through Mayer's own Singapore store that combines a DC-motor fan with HEPA-13 filtration rated to remove up to 99.97% of particles down to 0.3 microns, plus UV sterilisation and a filter-replacement indicator. Five air modes (auto, turbo, sleep, natural, normal) and auto left-right oscillation across 30/60/90/120°. During haze, when you want windows shut and air still circulating, having the fan and the filter in one machine genuinely helps, and at $289 it is $260 less than Dyson's TP10 even with Dyson's PEAK50 code.THE CATCH: the $39 replacement HEPA-13 filter (and its $59 two-pack) is still sold out, so buy a spare as soon as it returns rather than when the first one clogs.REST OF THE RANGE: the smaller MBFAP250 tower holds at $159 (U.P. $399) in stock, though its $50 filter is also sold out. The 42-inch MBFAP4236DRW with Wi-Fi is $299 (U.P. $499) in stock, and its $50 HEPA-13 filter is the one Mistral filter in stock. The MBFAP500 ($399), MAPF03 ($99) and smart MAPF32 ($249.90) are all sold out.BEST FOR: small flats that would otherwise buy a tower fan as well.
Up $30 (12 Oct), in stock: $289 (U.P. $599). 46" blade-free DC fan + HEPA-13 + UV, 5 modes. $39 filter still SOLD OUT. MBFAP250 $159 in stock; MBFAP500, MAPF03, MAPF32 sold out.
STOCK NOW: the Singapore brand most people's parents already own has run out of purifiers. On 12 October novita's own store shows the A5i sold out in both colours at $180 (U.P. $328), the A11i sold out in all three colours at $258 to $268 (U.P. $469), with its colour labels now pointing to mid-October delivery for Sand Beige and mid-November for Arctic White and Graphite Black, the A11i trade-in listing ($198 to $208) sold out, and the A18i sold out at both $458 and its $398 trade-in price. The one purifier still in stock is the flagship A8i at $1,898.WHAT THE A5I IS: a genuine H13 HEPA with a carbon stage rated at 337m³/h CADR, comfortably enough for a large bedroom or a small living room, backed by a local warranty, a local service centre and filters you can buy off the shelf. That is why it stays on this list for when it returns.WHAT TO BUY INSTEAD: novita's real speciality is 2-in-1 dehumidifier-purifiers, and the whole range is in stock: ND2+ at $398 (U.P. $569), ND25.5i+ at $488, ND26+ at $528, ND50+ at $698 and ND60i+ at $798 (U.P. $1,098). If humidity is as big a problem in your flat as the haze, one of these does both jobs from one plug. Free delivery on orders over $300, otherwise $12.BEST FOR: a damp flat, today, or a stock alert on the A5i.
A5i $180, A11i $258 and A18i $458 all SOLD OUT (12 Oct); A11i colour labels say mid-Oct/mid-Nov. In stock: A8i $1,898 and 2-in-1 ND2+ $398 (U.P. $569) to ND60i+ $798.
THE DEAL: the cheapest way to put a purifier in every bedroom at once. Sterra is a Singapore direct-to-consumer brand, and the Moon is its best-seller: HEPA-13, rated for 57m² at 280m³/h, near-silent at 20dB, with one-touch control and no app. The bundle gets you three Moons for $458, still buyable on 12 October in Space Grey; the Snow White bundle is still sold out.READ THE SAVING: Sterra prices that bundle against a $687 'total value', which works out at $229 a unit, not the $189 the Moon starts at on the same site, so the genuine saving is one free purifier, not a discount across all three. Single Moons are patchy: the Snow White ion model at $189 and the Space Grey UV model at $229 are in stock, the other two combinations are not. NEW: Sterra launched the Halo on 1 October at $249, a HEPA-13 and activated-carbon unit designed for small rooms, with real-time air-quality monitoring. The Twin Halo bundle is $448 with a free HEPA-13 filter (the filter alone is $59).HEPA-14: the Breeze Pro is $279 for one, $548 for two and $807 for three, and the pet-tuned Paws is $279 (U.P. $299) on the same ladder.GONE THIS CHECK: the Breeze Pro bundle with two formaldehyde filters ($558) and the Paws-plus-Flow-vacuum bundle ($368) have both been withdrawn, and the $159 Mars remains discontinued. Free delivery and installation.BEST FOR: covering two or three rooms in one order.
Buy 2 get 1 free: 3× Sterra Moon for $458 (U.P. $687), Space Grey in stock 12 Oct, Snow White sold out. New Halo $249 (1 Oct); Twin Halo $448 + free filter. Breeze Pro filter bundle and Paws-plus-vacuum bundle withdrawn. Free delivery & installation.
PRICE: the $200 markdown has gone. On 12 October Dyson's own Singapore store lists the TP10 at $599 with no price cut, but a sitewide code, PEAK50, takes it to $549, in stock with free next-day delivery on orders placed before 5pm Monday to Thursday. This is the most-moved price in the guide: $399 on 30 July, $499 from 4 to 16 August, $599 on 27 August, $499 on 4 and 12 September, $399 on 27 September and now $599 again. Six changes in under three months, so check this one page on the day rather than assume a direction.WHAT IT IS: a 2-in-1 purifying fan with a fully sealed filtration system: a 360° glass HEPA H13 filter that captures 99.95% of particles as small as 0.1 microns, wrapped in an activated carbon layer for gases and odours. Sealed matters, because what the machine traps stays trapped rather than leaking back out around the filter. Integrated sensors report air quality on the LCD screen, it oscillates up to 350°, and night mode runs it quietly while you sleep. Grab PayLater splits the $599 into four instalments of $149.75.THE COMPARISON: at $549 it is $260 more than the Mistral tower at #4 for the same two jobs.BEST FOR: sealed filtration plus a cooling fan, if the gap to Mistral is worth it to you.
$599 on 12 Oct, no markdown; $549 with sitewide code PEAK50. In stock, free next-day delivery. Sixth price change since 30 Jul. Sealed HEPA H13 + carbon, 350° oscillation.
The premium option, and the only one on this list where someone else changes your filters. Coway's Noble AP is the Korean brand's flagship air purifier for Singapore, running multi-stage filtration (a 4D pre-filter, a smoke and allergen filter, a 4D double HEPA and two deodorisation filters) with UV-C sterilisation across 66m², and it comes with the regular servicing visits every six months that are Coway's whole proposition: a technician cleans the unit and swaps consumables so the machine doesn't quietly degrade into an expensive fan. This price ran backwards earlier in September and has stayed there. On 12 October Coway's own air purifier listing still flags the Noble AP as a Special Offer, but the headline has gone back up to from $1,588 against a $2,038 usual price, where it sat on 16 August, after showing $1,349.80 on both 27 August and 4 September. The $1,349.80 entry price is no longer selectable. The practical effect is that the headline and the configurator now agree: the default outright, self-service, 1+1-year filters-and-warranty build also totals $1,588 at checkout, so the gap we warned about on the last two checks has closed, in the wrong direction. It is a lot of money next to a $99.90 Tefal, and for a single bedroom it is overkill. It earns its place if you want a single serviced appliance for a large space and would rather not think about filter part numbers for the next five years.
Special Offer: from $1,588 (U.P. $2,038), unchanged on 12 Oct. Multi-stage + UV-C, 66m², servicing every 6 months included. Headline and default outright config agree at $1,588.

We have now priced this list eight times on every brand's own Singapore store: 30 July, 4 August, 16 August, 27 August, 4 September, 12 September, 27 September and 12 October 2026. This is the worst the haze has been all season. At 9am on 11 October NEA's 24-hour PSI read 151 in the central region and 152 in the west, and at noon on 12 October it was still 146 central, 147 west, 133 east, 115 south and 103 north, all inside the Unhealthy band of 101 to 200 (what each PSI band means for your family). MOH has also switched on the Haze Subsidy Scheme from 12 October. This time the movement is in stock, not price.
What did not move: Coway's Noble AP stays at from $1,588.
Buying now? Size up: pick a unit rated for a larger area than your room, because you will run it on low overnight, and check the seller has replacement HEPA filters in stock before you commit.
If you want the short answer: buy a HEPA-13 or HEPA-14 unit with enough airflow for the room you sleep in, from a seller who can deliver it this week. Under $200, Tefal's Pure Air Mini at $99.90 is the cheapest machine you can get now for a small bedroom or study, and Mistral's MBFAP250 tower at $159 adds a fan, though its $50 filter is sold out. If you can wait for 11 November, EuropAce's EPU1200F at $139 and EPU3380E at $199 are still the best HEPA-14 value here. Between $240 and $300, Sterra's new Halo at $249, its HEPA-14 Breeze Pro at $279 and Mistral's MBFAP460 fan-purifier at $289 are all in stock. Dyson's TP10 at $549 with code PEAK50 is the sealed-filtration option. For two or three rooms, Sterra's buy-2-get-1-free Moon bundle at $458 works out at about $153 a room. A full 84m² living room has no in-stock answer on this list until Sharp restocks the FX-S120E-H at $799; Coway's serviced Noble AP from $1,588, rated for 66m², is the nearest you can order today.
The spread runs from $99.90 to $1,588, which sounds arbitrary until you see what the money is buying: room size first, then who changes the filter. Four bands, at the prices verified on 12 October 2026.
Then there is the cost the sticker price hides. Filters are the real running expense: $39 to about $99 a year per machine across the models here. Mayer lists the Mistral filters at $39 and $50 (the MBFAP460 and MBFAP250 ones were sold out on 12 October, while the 42-inch model's $50 filter was in stock), EuropAce lists its new HEPA-14 packs at $49.90 and $79.90, Sterra's Halo filter is $59, and novita's 24-month PuriPRO packs work out near the top of that band. In a haze year budget above that, because a unit running flat out through a smoky fortnight will not get twelve months out of a filter.
The rule of thumb that matters more than any of these figures: two $199 purifiers in the two rooms you actually sit in will do more for you than one $599 machine parked in the hallway.
Every unit here is sold direct by the brand, which is the short answer to where to buy. EuropAce, Tefal, Sharp, novita, Sterra, Dyson and Coway all run their own Singapore online stores, and Mistral sells through Mayer's. Buying direct is what gets you the local warranty, filters you can reorder later, and the promotions that never appear on marketplaces: novita's trade-in, Sterra's buy-2-get-1-free, Sharp's Mid Autumn Sale. It is also the only place the stock counters are honest, which during an episode like this one matters more than the price.
Offline, the same models turn up at Best Denki, Courts, Harvey Norman, Gain City and the department-store electronics floors, usually at list price but occasionally with a store voucher or bundled delivery that beats the online deal. It is worth a look if you want to hear how loud a unit actually is before committing, because spec sheets quote decibels at the lowest fan speed, which is not the speed you will use during haze.
What to avoid: unusually cheap Shopee and Lazada listings for the same model numbers. Air purifiers are a common parallel-import category, and a grey set typically means no local warranty and filters you then have to source yourself, which on a machine whose whole running cost is filters is the expensive kind of saving.
The complaint that actually drives people to buy mid-haze is the smell, and it is worth understanding why a plain HEPA filter does nothing about it. Haze carries two separate problems: fine particles (PM2.5), which HEPA traps, and gaseous compounds, which pass straight through a HEPA filter because they are not particles at all. Smell is the second problem.
That is what the activated-carbon layer is for, and it is the spec to check before you buy. A thin carbon-coated mesh is not the same as a real carbon filter, and it saturates in weeks rather than months. Sealed systems help too: Dyson's TP10 (#7) is fully sealed, so gases the carbon has captured cannot leak back around the filter edge. Sharp's Plasmacluster models (#2) take a different route, releasing ions into the room to work on odours that have already settled into curtains and sofas, which is where smoke smell tends to live once the air itself has cleared.
Practical order of operations during a haze episode: keep windows shut, run the purifier on a higher speed than feels necessary, and wash or air soft furnishings afterwards. No purifier removes a smell that is coming out of your curtains.
It's an official warning, not a sales line. The Singapore Institute of International Affairs released its Haze Outlook 2026 on 24 June 2026 and rated the region 'Red', meaning a high risk of a severe transboundary haze event. It is only the second Red rating since the annual report started in 2019 (the first was 2023), and the report names August and September as the peak danger period, driven by El Niño, a positive Indian Ocean Dipole and drier-than-usual conditions through to around October. It has since happened, three times. On 4 September 2026 NEA's 24-hour PSI reached 106 in the central region, inside the Unhealthy band of 101 to 200. It came back to 110 on 27 September, and on 11 October it hit 151 central and 152 west, the worst of the season, with every region still Unhealthy at noon on 12 October. MOH switched on the Haze Subsidy Scheme from 12 October for the first time since 2015. Stock is the practical lesson: by 12 October every Sharp purifier and novita's three main models had sold out. Buy between episodes rather than during one.
Haze and allergies pull in slightly different directions, and the machine that handles both is the one with a real carbon layer and enough airflow for the room you actually sleep in. Haze is PM2.5 plus gases, so you need HEPA and activated carbon. Allergies are usually dust mites, dander and pollen, which are larger particles that any HEPA-13 catches, but they need a high air-change rate to be cleared before they resettle. On 12 October that points at these picks. For the highest filter grade you can get delivered now, Sterra's Breeze Pro and Paws are HEPA-14 units at $279 each. EuropAce's two HEPA-14 models bring the grade down to $139 and $199, but they are pre-orders delivering from 11 November. For airflow plus carbon in stock today, Sterra's new Halo at $249 pairs HEPA-13 with an activated-carbon layer, and Dyson's TP10 ($549 with code PEAK50) is fully sealed. Tefal's PT2220 at $149 runs the best dedicated Allergy+ layer here, but it is out of stock again; its smaller Mini sibling is in stock at $99.90. What none of them fix is a bedroom with the window open, so during a haze episode keep it shut and run the machine continuously rather than in bursts.
Match the CADR to the room, not the marketing headline. A typical HDB bedroom is roughly 10 to 15m². A purifier rated around 200 to 280m³/h CADR (EuropAce's EPU1200F at 200m³/h, Tefal's PT2220 at 198m³/h, Sterra's Moon at 280m³/h) will turn the air over several times an hour with the door shut. A living room of 25 to 40m² needs 300m³/h or more: Sharp's FX-S120E-H (84m² rating), EuropAce's EPU3380E (338m³/h, 700 sq ft), novita's A5i (337m³/h) and Dyson's TP10 sit here, though on 12 October only the Dyson was in stock for delivery this week. One thing manufacturers don't say loudly: coverage ratings assume the room is closed. An open-plan HDB living-dining area with the kitchen door open behaves like a much larger room, so size up rather than down, and during haze keep windows shut and run the unit continuously rather than in short bursts.
Marginally, and less than filter size and airflow do. A HEPA-13 filter captures at least 99.95% of 0.3-micron particles; HEPA-14 raises that to 99.995%. Haze particles are PM2.5, well within what a HEPA-13 handles, so for most homes a HEPA-13 unit running at the right airflow beats a HEPA-14 unit that's undersized for the room. Where HEPA-14 helps is for allergy and asthma sufferers who want the extra margin (Sterra's Breeze Pro and Paws at $279, and EuropAce's new EPU1200F and EPU3380E at $139 and $199, are the HEPA-14 options here). What matters more during haze is a carbon layer, because haze carries smoke odours and gases that HEPA alone doesn't remove, and every unit on this list except the most basic includes activated carbon.
Filters are the real running cost and they're worth checking before you buy. Mayer lists the Mistral MBFAP460 filter at $39, the cheapest here, though it was still sold out on 12 October, and the MBFAP250 and 42-inch MBFAP4236DRW filters at $50 (only the 42-inch one in stock); EuropAce now lists its new HEPA-14 packs at $49.90 for the EPU1200F and $79.90 for the EPU3380E; Sterra's Moon filter is $55, the Halo's $59 and the Breeze Pro's $75; novita's larger units take a 24-month PuriPRO pack listed at $198, which works out to about $99 a year. Most manufacturers quote 6 to 12 months per filter under normal use, but that assumes normal air. A haze episode loads a filter far faster, and a purifier running 24/7 on high through a smoky fortnight can eat months of filter life. Budget for one extra filter per unit this year, buy it before the haze rather than during, and check whether the model has a filter-change indicator (the Mistral tower and most units here do).
Every price in this article was taken from the brand's own Singapore website, first on 30 July 2026 and re-checked on 4 August, 16 August, 27 August, 4 September, 12 September, 27 September and again on 12 October 2026, and that's deliberate. Marketplace listings for air purifiers are a common home for parallel imports and grey-market sets, which usually means no local warranty and filters you then have to source yourself. Buying direct also gets you the promotions that only run on the brand store, such as Sterra's buy-2-get-1-free bundles, Dyson's PEAK50 code, Sharp's seasonal sale pricing and novita's trade-in when its purifiers are in stock, and for Coway the six-monthly servicing visits that are the whole point of that model. Brand stores are also the only place the stock counters are honest, which on 12 October mattered more than price. Do compare, but check that the seller is the brand's own official store before you buy on price alone.
Buy now, from whatever is actually in stock. The PSI eased to 70 to 79 on 12 September, came back to 110 on 27 September and hit 152 in the west on 11 October, and each swing has emptied shelves faster than they refill: by 12 October every Sharp purifier and novita's A5i, A11i and A18i were sold out, and EuropAce's $139 and $199 models had become pre-orders delivering from 11 November. What you can get delivered on 12 October, in the order we would buy it: Tefal's Pure Air Mini at $99.90 for a small bedroom or study; Sterra's Halo at $249 or HEPA-14 Breeze Pro at $279 for a bigger bedroom; Mistral's blade-free tower at $289 if you want a fan as well, buying its $39 filter as soon as it restocks; Sterra's three-Moon bundle at $458 to cover several rooms at once; and Dyson's TP10 at $549 with code PEAK50 if you want sealed filtration. The sold-out Sharp, Tefal PT2220 and novita machines are worth a stock alert rather than a hurried substitute, because all of them have sold out and returned before. Whatever you buy, run it in the room you sleep in with the door and windows shut, on a higher speed than feels necessary, rather than moving one machine around the flat.
Look for two things beyond the HEPA rating: a generous activated-carbon layer, and a pre-filter you can actually pull out and rinse. Pet dander is a larger particle than haze PM2.5, so almost any HEPA-13 unit will capture it. The problem is odour, which is a gas and needs carbon, and hair and fluff, which clog a fine filter fast and shorten its life. Of the units here, Sterra's Paws ($279, U.P. $299) is the only one specifically tuned for dander and pet smells, using a HEPA-14 filter, and Sterra sells a five-pack of its washable pre-filters for $30. The Paws-plus-vacuum bundles have both been withdrawn. Otherwise, EuropAce's EPU3380E (#1) at $199 is the sensible pet-household choice if you can wait for its 11 November delivery, since 338m³/h turns the air over often enough to keep up with a shedding animal, and Dyson's TP10 (#7) has the carbon layer plus a fully sealed body so trapped dander cannot leak back out. novita's A5i (#5) fits too when it is back in stock. Whatever you choose, plan on vacuuming the pre-filter monthly rather than quarterly.
Yes, and in Singapore it is often the right combination, because they do different jobs and do not cancel each other out. The purifier pulls particles out of the air; the dehumidifier pulls moisture out. Running both in a closed room during haze is fine and is what most people with mould or dust-mite problems already do. Two practical notes. First, keep them a little apart rather than side by side, so the dehumidifier's warm exhaust is not blowing straight into the purifier's intake and confusing its air-quality sensor. Second, a dehumidifier is not a substitute for a purifier, because dropping humidity does nothing to PM2.5. If you would rather not run two machines, Sharp's own store sells combined units: a 30L 4-in-1 (dehumidifier, purifier, shoe dryer and laundry dryer) at $649 from $799, and a 2-in-1 dehumidifier-plus-purifier (16L/day) at $509 from $541, though that 16L model was still out of stock on 12 October and the 4-in-1 was down to its last unit. novita's ND2+ ($398, U.P. $569) through ND60i+ ($798, U.P. $1,098) range does both jobs from one plug and is all in stock, and EuropAce lists a 30L dehumidifier with a standalone HEPA purifier at $499 (U.P. $899). A combo unit is the space-saving answer, but a dedicated purifier will almost always move more air for the money.
