Aer1 Filter Replacement for Holmes AER1 Air Purifiers, 4 True HEPA Air Filters + 8 Carbon Booster Filters for Replacement Parts # HAPF300AH-U4R, HAP242-NUC

The filters were a great deal. Shipping was as promised.Will buy again next time I need them.

I purchased these filters as a replacement for my air purifier filters. They fit great, and do the job well. There is no odor, and I can tell that they do a great job after one day in my purifier. We have a lot of wild fires in our area, and these filters do the job of pulling smoke particles out of our household air. I can breathe so much better in my house, and I know that we won't be having health problems because of the smoke and dirty air outside. I will be buying more of these filters soon.

Good product

I was relieved to see they were similar to aer1. I ordered from another seller and was angry because what they sent wasn't even close. That was partly my fault. Even tho I know better, I somehow still believe people have a good work ethic, and I didn't open the box until I needed a filter. I bought them thru Amazon, but I can't find the order. I'd give them a really po'd review.These filters fit and seem to do the job. You can tell they're not the best built, but they do what they're supposed to do at a better price than Holmes. At least these guys sent filters that fit.

Great price and fit perfect.

We have used these filters for more than 5 years in our air purifier system. Easy to install and works very effectively.

They work well with Holmes air purifier, except the charcoal filter is too short too thick, I keep using original charcoal filter, I was it washing masking air dry

We’ll made
