Review on Honeywell FC100A1029 Replacement Filter by Nordic Pure: Improve Air Quality with Efficiency by Richard Alemayehu

I read other reviews where there were concerns about the size. What I didn't understand is that I've been using these filters for 4 years. I have a Honeywell heater and it fits perfectly! Just measure the filter you have now and look at the dimensions listed on the old filter. If the numbers are the same, you shouldn't have any problems. It's made of the same materials and built as each of the OEM models, but costs a lot less. With the money I've saved, it's convenient for me to change filters twice a year (every fall and spring). Living in Alaska next to a glacier where ice sludge forms in the air around me some days when the weather changes, it's important to filter the air through my system. stood 6 months. Visual inspection shows the filter's white filter membrane turning gray after 6 months - so that's my standard and proves THEY WORK! And I'm a lot happier to see the filter go gray than my heating system (and lings) to collect all that contaminants. SUMMARY: Like any expensive appliance, you need to take care of your heating system, and filters are an inexpensive way to do it. 5 STARS for efficient performance and cost effective essential product.
