Honeywell HRF-A300 Pre Kit air purifier filter, HPA 300, Black

The pre filters fit my Honeywell perfectly. They arrived with no bad smell, have a nice thickness to trap dust, dog hair etc, and so easy to use and change. Amazon has the best price I have been able to find and will continue to purchase.

Fits my air cleaner. Works great, what more can I say.

Happy to find 4 filters at a reasonable price. We really appreciate the air filter and find that there is so much less dust around especially for a severe asthmatic. The only drawback was the price of replacement filters so we were very pleased to find a box of 4 which is a year's supply of the A filters at a reasonable price. They fit perfectly and were easy to install.

Honeywell pre filter multi pack saves money vs. buying a single filter. Compared to generic brand and there is no comparison. Honeywell is far superior. Removes dust and odors wonderfully. Pre cut so very easy to use. dust adheres to filter to keep room healthier and fresh smelling.

I was have a very hard time finding the proper pre-filter to fit my Honeywell Insight HPA5250. The included manual gave filter model numbers that simply do not fit this unit. As the manual was for full line, it looks like they only gave the smallest filter part number. I decided to shop by size instead and chose this 4-pack which is for the the largest unit in the Insight line.Using the old filter as template, i trimmed to fit and solved the problem. I ended up with enough left over to also replace filter in my old HPA-051c! I will be able to replace filter in my HHT-011c as well with left over trim from next Insight replacement.
