I've had these for over a year and they work very well. We aren't an allergic family so I couldn't tell you how it is for allergies but compared to regular filters this is more restrictive. I'm not sure if that's a good thing. I can tell the increase airflow difference when switching my spare regular filter with this filter when cleaning. I just spray it with a water hose and wait 24 hours to dry.

Do you use the cleaner they advertise to clean the filter? This is a nice price for a permanent filter but the CEF cleaner is $25 a bottle

No I've never used it.

Thanks for the info. Sorry for all the questions, but do you just hose it off then? Is it easy to clean? Want to know before I commit

Yes that is all I do. Dust will just wash away. You will see clumps of gray stuff just wash away. It's very easy to clean.

More restrictive is a bad thing for HVAC actually. Proper balance is critical for a well performing efficient system. Besides refrigerant pressures which I think most people loosely get, air flow, static pressure, etc are also just as important. Doesn't mean your instantly going to kill your system or cause comfort/performance issues like coil freezing over and stuff if it's not a very excessive restriction, but any restriction above what the system is designed to handle will certainly degrade efficiency and performance as well as increase strain on parts like the blower motor more and more the further beyond spec it goes.

Thanks for the info. I'm thinking I noticed a difference was because I was replacing my dirty filter with a clean one. I will probably recheck it after I clean the filter.

FYI, all electrostatic filters produce ozone. The only ones that don't are purely mechanical: pushing air through a standard MERV or HEPA filter.

I even bought an ozone + UV lamp; turn it on for half an hour after I leave each day; the ozone goes away a few hours before I get home.

An electrostatic filter cleaner by Allertech is about 35% cheaper at $16.99 - https://www.natlallergy.com/aller...eaner.html

Oh and 10MEMDAY knocks off 10%

Please read the first sentence, I emphasized the first word:

"...Some devices that are advertised as air purifiers purposely emit large amounts of ozone...
...Air cleaners that utilize ionizers and electrostatic precipitators are other types of devices that emit ozone, but do so as a by-product of their design and function. These devices are designed to electrically charge particles in the air and cause them to attach to surfaces in the room, such as walls or floors. Ozone is released through the charging process, although these devices typically emit much less ozone than ozone generators..."

Air filters are passive, create just enough of an electrostatic charge to help particles to stick - I highly doubt there would be a detectable difference in ozone level.

Yup. It's a polyester filter shoved between a metal holder. They're beyond garbage, inefficient and ineffective. Avoid them. A polyester filter is just junk and there's a lot of added metal from the frame adding restriction. Together you get less area filtered with a junk filter and eventually an evaporator coil with built up junk on it. I dealt with these 20 years ago and had no idea they were still around.

This guy kno s what's up

Every AC person will tell you to not go above merv 10.

Your central air or heater are not meant to be air cleaners, it's to prevent dust from collecting and damaging your system

You can install an actual air filter at the unit that is designed to clean air but not restrict your system. Or buy independent air filters for inside your house... Winix goes on sale for $100 all the time and has way better filtration then some dinky 1" merv 14 you'd buy.

I laugh every thread someone posts about a 1" thick high merv filter. Not one AC tech would ever install anything more than merv 10, most recommend merv 8!!!
