Have been using Honeywell products for 4 years now. Air purifier and humidifier. The filters and machines are well made and do a great job. Living in CA with fires, allergies and occasional asthma and now our recent COVID, I am so thankful to have Honeywell products so available.

They should bundle up about five of these and sell them for a more reasonable price. They work great and do a good job on Honeywell humidifiers.

I have always used these filters in our humidifier and have been very pleased with the durability. I have tried other off-brand and cheaper ones, and you always get what you paid for...Excellent filters for a reasonable price.
