BLUEAIR 400 SF SmokeStop Filter, F400SM

These function well (with the appropriate Blueair cleaner) but the price is pretty steep. Not sure £99/year is what I should be paying for filters?

much too expensive for a cardboard construction product

Not cheap to replace but Amazons option to pay 0% in four instalments made it a breeze

Expensive but works very well. It has to be replaced every 6 months in theory but in practice ours gets replaced every 4 months. We live next to Bushy Park and get all the pollen, traffic pollution etc

All good thanks

you can get the same in EU for half, and you saying no taxes in ae, yes no taxes but prices are hiked

You're probably completely shocked that this Smokestop Filter costs as much as it does. But trust me, if you have any problems with odors, it's worth EVERY penny. I normally use the regular Blueair filter for the 402, but I purchased the Smokestop after my neighborhood was flooded with horrible fumes from a nearby methane gas leak. The authorities deemed the gases as harmless, so no evacuations were ordered. However, being very sensitive to fumes of any kind, I became very ill. With no other place to go, I put the Smokestop filter into my 402 and moved the air cleaner into my smallest bedroom, where I camped out for the next couple of days. A trip to any other room of the house left me feeling nauseous, dizzy, with a raging headache and difficulty breathing within minutes (but the fumes were "harmless"!!). The room with the Blueair equipped with the Smokestop filter was absolutely free of odor. It was incredible. Since not everyone has methane gas leaks permeating their homes (thankfully!), you may never get the chance to test the filter in this way. But it no doubt works wonders with cigarette smoke and other offensive odors that waft into your home. The filter has 2 "chambers." One filled with activated charcoal, and the other with the familiar Blueair patented white filter. So it doesn't just stop with odors, it still cleans particles from the air with great efficiency, and best of all, Q-U-I-E-T-ly. Just remember to change it after 6 months, even if it means going back to the regular (and cheaper) filter. Happy breathing! SEPT. 2008 ADDENDUM: I had another fume problem, this time, toxic deck sealant fumes from a home repair seeping into the house. I purchased another Smokestop filter and this time I noticed an odor coming from the filter itself. It's not horrible, but I had become so sensitive to odors after a week of sealant exposure that it made me feel sick. I left the Blueair on high and it has reduced the smell after a few days. To be fair, despite the filter smell, the deck sealant odor was neutralized. And finally, I have a balcony-smoking neighbor, and as soon as secondhand smoke wafts into my bedroom, I turn up the Blueair and the smoke odor is gone in a flash. Just be aware of the initial odor from the filter itself. I'd say I'm dropping my rating to 4 stars, or 3.8 if I could.

Me costó un poco acostumbrarme al olor del filtro. Empecé poniendo el purificador en lugares donde yo no estaba, pero ahora ya no tengo problemas. Es un poco mas oloroso que otros filtros de Blueair. Sólo lo notaran personas muy sensibles a los olores. En general es un buen producto.

Molto utile per chi ha la macchina per filtrare aria, fatto molto bene, come l’originale, l’ho consiglio

半年間ノーマルのダストフィルターを使っていましたがニオイが取れないので今回ニオイフィルターを投入してみたところ…素晴らしい性能です。あっと言う間に脱臭します! ただし私の部屋は6畳です。6畳に450でニオイフィルターを使うと圧倒的です。 使い始め数時間はフィルターや活性炭のにおいがしますが、すぐ取れます。 値段相応の性能と思います。
