GermGuardian 743 Sq. ft. Tower Air Purifier with HEPA Pure Filter with activated carbon. It's pretty great!

No I don't hear anything except soft white noise. I love it. I think it was around $70 on Walmart. 

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.

I have 4 cats and one LR3. I found that whenever i start to smell pee it’s because someone has peed somewhere that’s not the box. I have found those 2 spots so I know right where to look. Before I realized this was happening one of the spots the pee got into the hard wood floor. Thankfully I was able to get the smell out with natures miracle. The other spot he would pee was right on the side of the litter box and close to the floor so it would just run under. After the floor scare I put a plastic mat under the box and the pee doesn’t absorb into anything and I think that makes a super noticeable smell. We have gotten the peeing under control thankfully. I’m always paranoid about the smell, like I just notice it clean or not. I put a purifier in the room with the box and I don’t even notice it anymore. I think the purifier is like a germ guardian or something. It works wonders.

The best bang for buck is germ guardian, and the parts are replaceable if something breaks. They sent us a replacement part for one of our units for free, no official warranty or anything. We have 3 of them that have been running for a decade in our house.

Germ Guardian!!! I just changed the filters in mine, one at 6 months, the other after 3 months. I've never seen a filter accumulate so much dust! They really make a huge difference.
