If you want heating or air conditioning HVAC air filters MUST let air flow through them!
There are two philosophies on HVAC air filtration -
1. Use the real cheap ones, let air flow more easily, and the system operates more efficiently.
2. Use the expensive, high filtration ones, which restrict air flow, but keep the system cleaner.
With the second choice you MUST replace or clean your filters very regularly. I treated that subject in a blog many years ago which you can read by clicking here.
HOWEVER, it isn't often that you can find a high-filtration filter which ALSO allows great air flow. But I ran across such a filter very recently!
Combining the best of both worlds is this beauty!
I have to admit that I don't think I've ever seen such a filter before.
And I have been doing home inspections for a couple of days now!
You'll notice that this homeowner has selected a high-filtration filter, to keep the unit clean as possible.
And looking inside there you can see just how well this one has been working to keep the unit dust and dirt free! It is spic and span!
But yet, with utter foresight, the filter selected ALSO provides excellent air flow!
When I first saw it I had to wonder if it isn't something this homeowner had purchased from Billy Jays, who's products are legendary for improving the home living environment.
It sure looks like something Billy Jays would sell! And scream "Call now!"
You can also see a blue light hue on the filter. Underneath it this diligent homeowner installed an ultra-violet, air-purifying system to eradicate whatever the ultra-violet, air-purifying system is hopefully eradicating from the air!
There is not much as comforting as seeing a homeowner who wants to keep the unit clean, the air filtered and the home's air safe!
My recommendation: as much as you look, you may not be able to find this filter in the store, or even on line. It is exceptionally rare. All kidding aside, THE AIR FILTER IN THE HVAC UNIT MUST BE CHECKED, CLEANED OR REPLACED REGULARLY! Ideally that is done every month, but there may be a couple of months during the year when the filter isn't used so much as the system does not turn on and off so often. However, diligence is diligence. AND HOME MAINTENANCE REQUIRES DILIGENCE!
