- 240 Replacement Filter - Genuine Puro Air 240 Filter Replacement - Official PuroAir Air Purifier HEPA Filter with CarbonTech Filters 99.9% of Pollen, Dust, Pet Dander, Smoke, Odors

They work well. They keep the pet dander down in smaller areas. Easy to replace the filters. Very sturdy. Noise level great on the lower settings. Still not offensive on higher settings. You do hear it at higher speed settings.

Well, we haven’t used the replacement filters yet, but we really like the Puroair machine. Feel that it works well to clean the air. No more constant sneezing from seasonal allergies! Bonus-the soothing sound-better than a sound machine.

Perfect fit and functioning as expected. Thank you. Great price.

It's a replacement filter. It works well. The air purifier itself works great, just needed to replace the filter. I consider myself to be a more than clean person but these purifiers improve the house's air quality CONSIDERABLY. Love having one in my bedroom - it's quiet and helps me sleep like I'm dead.

The air in my house is so much cleaner since I started using the PuroAir 240 air purifiers! I just replaced the filters for the first time and it was an easy procedure. I’m really happy with this system!

Really didn’t understand how well it works until I changed the filter. May try an alternative due to cost- happy with the results but not the price.

Keeps the air clean. Helps with my allergies. And also no need to dust furniture as often. That's a plus.

A little pricey, but performs beautifully, eliminating cat odors and reducing allergens.

The air improvement was immediately noticed. The dust has almost vanished. Runs quite

Appears to work well.

This is the right filter. Perfect fit and materials. The extra cost for the quality is definitely worth it.

its quiet and doesnt take up a lot of room

It’s a bit pricey
