Nispira TPP440 TPP440F Filter Replacement for Envion Therapure TPP540 TPP640 TPP640S AP200 Air Purifier True HEPA with Activated Carbon, 2 Packs

Fits in my air purifier perfectly and as far as I can tell it’s doing exactly what it’s supposed to do!

I was happy to come across these on amazon for my Therapure air purifier. They are easy to install and remove and last a long time. I'm pleased with my order of these and will purchase them again.

I feel so comfortable and relieved with this product in my air purifier. Apartment air, feels healthier, with less airborne allergens in the air. Also eliminates the occasional spice heavy aromas from cooking. I highly recommend this product.

Works well enough, as far as I can tell

Great system!

We've been happy with these filters, and when we swap them out, they are trapping many particles in the air.

perfect fit!

Filters fit device

Replaced filters in both air purifiers. This product good value and seem to be working well.

Product fits for what I needed it for. Should be packaged better as one of the two came damaged.
