FiltreteA D H Advanced ALLERGEN Room AIR Purifier Filter HEPA Honeywell Holmes

I love that these filters fit my Holmes HAP9423 Air purifier that holds 2 Aer1 filters. The original Holmes filters are installed by 2 hooks on the filters and corresponding anchors on the actual unit. These Filtrete filters do not have the hooks, and instead are secured by two thin strips of adhesive tape, and that is my only complaint. The adhesive is not quite strong enough and so there are a couple tiny gaps, where unfiltered air will flow which could potentially dirty up the motor and fan area of the units. I am sure I could remedy this issue with some double sided tape, but I am going to let it be for now and see if it becomes a problem or not. I like that these filters cost me about half of what I would pay for the Holmes brand, and I have always liked Filtrete brand so I am sure the performance is top notch.

These things are awesome and cleaning the air in my room. It definitely helps with my allergies. Just pop the front of the air filter off and set them on and close the lid. It takes maybe 1 minute and then you are good to go.

During our smoky wildfire air the stores were sold out of filters so ordered these online. A little more expensive but arrived and did the job.

I'm so glad that I purchased these on Amazon they are less expensive than Walmart or Target. These are very good filters

Upgrading to a true HEPA filter not only cleans the air, but helps sanitize the air you breathe.
