Filter advertised as new but product shows it as used
Always like to keep a stock of one extra filter so i dont have to worry about interruptions. Upon installing it, the blueair filter lit up red and the application stated it has already been used up.

Seems genuine, but direction of air flow seems incorrect
Direction of air flow arrow is incorrect as it directs you to put the carbon filter ahead of the particle filter. This does not make sense and is inconsistent with the BlueAir video. Not sure why a genuine filter replacement would have this error...

Easy to load.

Expensive
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?

Saved Me From Horrible Fumes!
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.

En general es un buen producto
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.
