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

Everywhere I looked I had a hard time finding a replacement filter for Envion Therapure tpp630 model. But after some research gave this a shot. It does fit the tpp630, even though, it does not say this model number in the description. Now, it has been a while since we changed our filter but after swapping it out, the filter works and now the air purifier is extremely quiet when on the lowest setting. We are very happy with this!

Perfect replacement. Fits nice and snug and seals where it is supposed to. Honestly looks just like the ones that come with the unit, same construction and everything. No air flow issues and does not cause an error with the filter sensor inside the unit. I looked on other sites and they all wanted this price for just one.

I’m so happy with this product,thanks

These fit my air filters and worked fine. We definitely needed new HEPA filters, as I'd vacuumed the old ones many, many times, over at least 10 years.

good quality and at a reasonable price

These filters will last up to 6 months if you vacuum out once a month with just a regular brush head on your vacuum. If you do not have one then it will last two to three months depending on the air.

I was glad to find filter refills so would not have to buy a new air cleaner .
