My HVAC company is having a hard time getting ahold of filters for my system due to the fires here in CA and Covid. After two months of waiting for them to bring a filter I decided to try my luck with this one on Amazon. It’s not as dense as my previous accordion style filter which fits in a plastic frame, but it is the same size and fits my unit. Its lack of the same surface density has me questioning if it’s truly a MERV11. But since I can’t differentiate between the differences, it’s clear that I obviously know nothing about air filters, so I’m just gonna say “it’s close enough” for my liking and I’m gonna cross my fingers and hope that it works like the old one did. It did arrive slightly crushed in one corner which is likely the result of handling from the carrier. Either way, since I can’t get a replacement filter at a box store [they are wiped clean…plus they don’t carry this size anyway], it’s better than my dirty, dusty and smoke filled filter. On the upside it was 25% cheaper than what I usually pay for my filters through my HVAC company. The filters I get from the HVAC company are designed to last about six months, so I replace them twice a year. If this filter from Amazon lasts six months then I’d say it’s an excellent value for the money, but if it doesn’t then I’ll go back to the more expensive filters from the HVAC company which are true Lennox parts and seem to be of better quality.

I have a relatively new Lennox furnace with a Healthy Climate filter module. After using the two filters the installer left I purchased another brand that was advertised to fit. It was difficult to install and I needed to cut it to remove it. The next year I ordered another brand, again one that also claimed to fit the Lennox system. This time I could not get it in at all. I finally ordered the Healthy Climate filter. When it arrived, via FEDEX, the box had a big hole that had been taped over. On opening the box I saw a portion was severely crushed. I called the seller and they promised to ship a replacement immediately. This time it came double boxed! I installed it and it slid in beautifully. I have a particle monitor that I use in my workshop. I brought it up to the living space of my home and turned the furnace blower on to circulate the air. Within a few hours I measured a drop in half of the measurement of fine dust. Great product and great service!

Me gusta el hecho que el filtro se ve bastante robusto fuerte y bien hecho algo que no me gusto es que no traiga tan siquiera una flecha o algo que diga este lado arriba o abajo donde o de que forma va me toco ver un tutorial en YouTube pero en fin por elPrecio seVe que está bastante bueno

Not much to say about an air conditioner filter lol my AC company says it works fine and they change it for me once a year. It’s much cheaper to buy it here on Amazon then from your AC company.
Ginny Lewis –
When our airconditioning/heating systems are checked twice a year, they suggest we replace the filter. If it keeps our power bills lower for more efficiency, then it is good to have it changed.
