Real stories from families that count on PuroAir filters

We got the PuroAir 400 a few months ago, and our air has never felt better. The filter subscription is great and so convenient.

Three filters in, and it’s clear they’ve been working overtime. This is your reminder that what you don’t see is exactly what your filters are trapping. Time for a fresh set - no wonder air quality feels better after a change. Definitely staying on top of replacements moving forward.

Our son recently went through a bone marrow transplant. To be safe, we ordered one 400 model and 2 240 models. We have been so happy with them. They are quiet and clearly they are working! It brings us peace of mind while our son continues to heal

I have really bad allergies and this has significantly helped me. I definitely plan on getting another one soon. It’s simple and looks great.

We bought 2 purifiers to run in our room because the dust and everything else was holding that room hostage. I'm submitting a picture of one of the filters showing how bad the room was and how good our PuroAir has been cleaning out years of neglect! We love all 5 of our PuroAirs spread throughout our house!

My son and I have allergies. With the help of OTC meds and this purifier, we no longer suffer! In 2024, my son had countless sinus infections. We purchased our PuroAir 240 in January of 2025. My son has not had a single sinus infection since, saving us time and money!
