Review on Nispira True HEPA Filter Replacement for Envion Therapure TPP440 TPP540 TPP640 TPP640S Air Purifier - Comparable to Part TPP440F, Pack of 2 by Carl Lee

Revainrating 5 out of 5

The air filter is good for heating, cooling and air quality

We have had them for 3 years - 1 in every room in our house. Helps tremendously with air pollution as we live in the valley. Easy to install - with a subscription, it will be ordered and delivered exactly when we need it, no problem.

Pros
  • Availability
Cons
  • I have no negative feelings about it, everything is fine
