ProHEPA 9000 HEPA replacement filter Compatible with VEVA ProHEPA 9000 Air Puri-fier, Including 4 True HEPA Filters & 8 Carbon Filters

I like how it cleans the air, You can see the particulates in the screen and filters. How often you change the filters and clean the screen depends on your activities in the spaces you're filtering. This varies from user to user. So, I cannot say for someone how many filters you should use or how often you should clean the microfiber screen. In my house, that varies.

Just the right size and works great!

These filters are a great value for how many you get . They perform well in my purifier and don’t have any weird chemical smell . They are easy to use and fit perfect .

Bought these HEPA filters for replacement filters for air purifier we have. Because I seem to go through them a little faster than others living in the woods on a dirt road and heating with an indoor wood stove does create a lot of dust and pollen in the spring time. Seems to be just as good as the original filters it came with.

Product works great, I now have bought two

Great replacement filter. We have 2 dogs and 4 cats, and these do a great job keeping our house air clean. I generally wash and reuse the black pre-filters several times. The white paper filter can't be washed, but I knock the dust out of them and gently clean them with my air compressor once or twice before I replace them. The pre-filters do a great job catching most airborne debris.

Great product
