Purivortex AC400 Air Purifiers Multi-Effect HEPA Replacement Filter, 3-in-1 Filter, White

Great!

I love these filters. They run very quietly even at the highest setting and last about two months running at nighttime. When the red light comes on to let you know it's time to change it out, they are very dirty compared to the new one. It also makes the room cooler from the cool air that flows out from your machine. I really love them for the price and quality.

I love these air filters and they really work. I have two now and the filters are easy to change if you're strong enough to twist off the bottom (I wasn't). There really isn't anything else to say except get one if you want your house to always smell fresh. The filters I have used lasted four months, but for a fresh, clean smell; it was worth the price.

I love this product actually I’m just about to buy a couple more. They last forever, considering the amount of debris that’s in your air in your personal space. And mine there’s a lot and they worked great.

If you are going to run a HEPA, replace your filters. These were great during the smoke in the northeast from the fires in Canada - particulate levels in the house were very low partly thanks to the two units I have in the main living area. These are great, fit well, and do a good job picking up dust and fine particles.

This item was small but I put it in a child's bedroom. It runs quietly and the soft color light makes a great nightlight.Just plug it in.. that's it.

Nice
