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 Movahed

Revainrating 4 out of 5

Fits great, air performance is slightly reduced.

These replacement filters fit exactly like the original filters you won't find anywhere else. The only downside is that the airflow is reduced a little more than with the original filters. I wish I could buy additional original filters if they were available. The car was only 2 years old before the filters ran out. That is not right.
