Review on 🔘 High-Quality HPA300 Carbon Pre Filter Replacement (4 Pack) for Honeywell HPA300 HEPA Air Purifiers - USA Made by Gerald Reeves

I bought these pre-filters for my Honeywell HPA300 HEPA Air Purifier. I bought the pre-filters and HEPA filters at the same time as the air purifier so I have them on hand when I need them. I purchased the air purifier on December 23rd 2020 and yesterday about 3 months later on April 1st 20201 the red pre-filter replacement light came on. I opened the door and the pre-filter was dirty! I am amazed at how well the device filters. This replacement pre-filter will fit, but is noticeably thinner (not by much, but noticeably) than the original filter that came with the unit. Seems like a decent budget option. However, you may end up changing the filter more often, so you may not end up saving as much. I will be buying Honeywell pre-filters in the future. I spent a little more to buy a quality air purifier and it doesn't make sense to me to skimp on the quality of the filter just to save some money.
