AC5300B Elite 4-in-1

I use [this](https://www.homedepot.com/p/GermGuardian-870-sq-ft-HEPA-3-Speed-Tower-Air-Purifier-28-in-in-Black-for-Home-UV-C-Wildfire-Smoke-Dust-Odors-Allergens-AC5300B/206868649) purifier with their pet filters for my bird room. Filters last about 6 months, but it got my cockatiel to stop sneezing all the time.

With that in mind a germ guardian tower is probably the most affordable good option. Whatever you buy should have UVC light built in to degrade mycotoxins, “plasmawave” or “bipolar ionizer” is also an acceptable alternative just make sure it’s California CARB certified. Stay away from classic ionizer/ozone

I do. I have 3 school aged kids aka plague carriers. We have Germ Guardian UV-C plus HEPA filters in each room. It greatly cuts down on kids reinfecting each other and us parents. They also collect cat hair pretty well. The Germ Guardians were $98 each and 4pack of replacement filters is $30. Saving one doctor visit for the 3 kids covers buying a unit.

Blues air or GermGuardian with UV. I’ve had mine for years and it’s been great

For less than that I got two germ guardian hepa air filters, and a Bissell hepa vacuum.
