I’m very mold sensitive and have found that air purifiers can help with mold but don’t really fix the problem. Mold collects on the hepa filter and then the filter becomes an issue. Some of the more serious machines have helped by directing uv light get at the intake side of the filter though, like tracs and enviroklenz. Some of the smaller machines that helped a little bit initially are germ guardian 5 in 1 and intellipure.

Look under the cabinets where the pipes come in and see if there’s gaps. I had an apartment years ago where the smell from the lower unit was coming in through there. They put some spray foam in to block it off and it helped immensely. I have germ guardian purifiers with pet filters that I’ve had for years and they help a lot with allergens and I also smoke cannabis and it helps with that too (I live in a house so it’s just me, but it helps circulate the air and get cooking smells and cat dander out of the air too).

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.
