Lennox X6675 MERV 16 Air Purifier with Media Filter

Marsha R.: Just exactly the brand and size we needed. Our heating tech didn't have one with him last week when he was performing our annual furnace check. He was going to order it, but it was going to cost even more than last year. I told him to hold off, and I decided to check out Amazon instead. Sure glad I did! The same exact one, cost less and I got it the next day! This vendor gets an A+ from me! Will definitely order again.

L. Varin: Easy to install but that is actually a feature of the furnace I have. This is a well constructed filter and I need only replace it once a year.

Simon Hu: It is a part of the Lennox air conditioning system and therefore the reliability and quality has nothing to do with Amazon. Amazon provides the best price from the Google search and thus the price is good. Delivery uses FedEx instead of Amazon. Amazon delivery is usually faster but FedEx delivery is good too.

William G. Finley: This will be a pretty long review for a furnace filter but, it seems there is a lot of confusion around them and this one in particular. I'll try to clarify. TL;DR - if you check independent testing out there this is probably the best filter you can buy for your furnace and it does so with a very modest pressure drop (more on that later).

SIZES

Unfortunately, the HVAC industry loves to confuse people about this. By my count, there are no less than FOUR different filter sizes out there for filters labeled 20 x 25 x 5. So, what size is this filter REALLY? It's 19-3/4 x 24-3/4 x 4-3/8 (even one of Lennox's websites has a typo on this). In the industry, they tend to round up if the size is ANY fraction above the whole number.

This is a LENNOX filter, "Healthy Climate" is Lennox's line of HVAC parts and accessories. It's specifically designed to fit Lennox's HCC20-28 air cleaner box. This is the ONLY box they certify it to fit in. Now, with that said, other manufacturers (Honeywell, Carrier, and others) use this same size as well, and they're listed on the filter (I'm not listing them here, look at the photo).

So, check to see that you have...

james: In my last house i put in a 20 seer lennox system and loved it. This house i have a ruud with a honeywell filter holder and the handler calls for a 5 inch filter. The big box stores do not have this high of a merv. I found this one and it fits like a glove in my honeywell box with no issues. This is my 2nd year using this filter (2nd one) and i have no complaints about it. It does its job and i will continue to buy each year.
