6 STAGE ELECTROSTATIC AIR FILTER HOME WASHABLE PERMANENT LASTS A LIFETIME FURNACE OR A/C USE NON-RUSTING ALUMINUM FRAME HEAVY DUTY HIGH DUST HOLDING CAPACITY JUST RINSE DRY & REUSE (20X25X1)

Seems to work great. We have 5 cats and 2 dogs, hear and dandruff is an everyday life for us. Our vent is on the ground so it sucks up a lot of that and this filter seems to catch everything. No idea about the tiny particles but from what it says it has a static charge that attracts those things too. I would go through two filters a month but since this one can be washed and reused, it's a lifesaver and most importantly a money saver!

The easyness of installing and taking out to wash. No need to Ever buy filters again. Great price! Great product! Plus it cleans the air for better air quality for those with breathing problems.

Filter arrived earlier than expected and was in great shape out of the box. High quality product with good craftsmanship. The filter fit perfectly into the air return recess. If the filter works as good as it looks, I will be very pleased.When I opened the box there was a typed note from the owner which he had signed. He explained the thought and materials that went into the filter. He had his personal email address included if you experience any problems. I was extremely impressed.

I installed the new air filter 45 days ago. The airflow is strong. The air is clean with less dust in the house. Previous disposable filters would only last a month or two before they would restrict the air flow. I’m very happy with the quality and performance of this product. It will pay for itself in one summer.

aluminum one piece frame riveted together, solid webbing for filtration. As with any reusable hvac filter it is undersized and requires you to put a strip of weather stripping around it so it fits with a seal in the HVAC return housing tightly holding it and forcing air through the filter not around it.

I bought this to go in front of my standard filter, i got a thinner filter so I could fit both. After 2 months thing was filthy and the filter behind it had hardly any dust on it at all, maybe an imperceptible amount. I think this metal filter will last forever and my secondary filter wont need to be replaced for several years instead of every two months. It took 2 minutes to hose it off. Very satisfied and amazed at the amount of dust that this filter trapped

Perfect fit for our system, shipped quickly and arrived on time

I am checking to see if the product improves the air quality at home. In the mean time, I do not like the business in branding foreign products as of poor quality and 100% US Citizen made as superior. That is either a marketing gimmick or a bit narrow-minded for me. As a "foreign" legal worker in the US, I believe the market is smarter and knows more than that. Let the consumers be the judge.
