It's an HVAC system not an air purifier. Please use the highest merv filter you can find, keeps HVAC guys in business.

The air filter in an HVAC system is to protect the system, not to clean the air. Restricting it with higher efficiency filters will destroy the systems efficiency first & eventually cause failure.

Typical residential HVAC system is designed for a Merv 7 or 8 air filter. If you put a higher Merv in it, it will not move enough air to efficiently heat and cool your house, and you will eventually burn out your fan motor.

The bigger the number on the merv filter. The sooner you'll get a visit from me. Get your checkbook ready, airflow airflow Airflow, a tip for those who care UV lights.

HVAC contractor here. I would not recommend a high merv filter. It puts a strain on your blower motor. Imagine putting your hand over you vacuum and hearing the motor rev higher it’s the same principle. The higher and harder the motor revs the more amps and heat and strain that the motor will be exposed to.

HVAC filters are for the machine, not for air quality, merv 8 is more than enough. If you want to purify the air get a machine for that purpose.

yes it all sounds good. this is the part that you all don't say anything about. those higher end Merv filters you legitimately have to change them once a month or earlier cuz they're plugging up your system. those filters cost like $25 as filter for a filter that's destroying your air conditioner.

Looks good until you realize you're restricting air flow causing the unit to work harder.

Dona Holt Decker :
Restriction of air flow is just as damaging as dirt. Please don’t use higher than Merv 11 unless you want to become besties with you HVAC guy.

The man # 98 :
what a misleading video..... they should let us know which a/c unit is designed for a merv-15 filter..... must people use either a mini split or window unit which only uses a mesh filter.....

The higher the Merv rating the higher the air restriction.

do static pressure test for each filter

Ac is for air flow not to filter air.. get an air purifier if you want that.. Just going to shorten the life span of the air handler.

the higher the merv, the more 'restriction' too.

The higher the rating, the harder your HVAC is going to work. If you can have purifiers in your house instead, that’s the better way to go and use a lower MERV rating in order to save money on your AC as well as keep your HVAC running smoothly. There’s only one time that I will put a high rated filter in my HVAC unit, and that is when there are forest fires around and that smoke can come throughthe HVAC.

user3541489941051 :
do not ever use anything higher than 8 ever after 8 the restriction of air flow raises the static pressure and the unit will die faster it will not last as long

use merv 8 and change every three month or as often as you need to. you cant cool or heat air if its restricted Hvac tech here

It’s a single-family home, not an Intel cleanroom. MERV 8–11 is plenty!

That is fantastic now you should test for airflow restriction
