Very Happy About my Product

So happy about my Honeywell Filters. It is very hard to buy from the big stores in my area . I would have to go to two or three stores and could not find the filters I needed. Ordering direct is so much better and the high efficiency allergen MERV filters keeps the quality of the air in my home really clean compared to a previous competitor. Customer service is very good also. Price was very good also for top quality product. Thank you. You made my life less complicated these days. Thank you, again. S.V.

Best Filters

The quality of these filters is top notch. They do everything they claim to and last a good while. I urge everyone to buy them directly from Honeywell. Retailers sell these filters for 2-3x the price, and the only difference is that the retail versions have more color/graphics printed on the packaging/filter housing. No reason to pay extra for something you look at for less than a minute when opening and installing. If you're putt off by the shipping cost, know that its more than covered by the base price savings. Plus you won't have to deal with receiving bent/dented filters, which often happens with Amazon, home Depot etc.

HVAC Filters at a good price

Ever since the Pandemic the cost of HVAC Filters has doubled. Honeywell keeps the cost lower than the big box stores and the product is the same or better. Great deal!
