Anybody using or thinking about using the K&N Home Air Filters? I had a K&N gift card & decided to use it to purchase the home filters.

Not home air filters, but might be worth a look?

Y E S !
Been using them since the fires. We were changing filters weekly. Really like them.

I have one and it doesn’t have as much dirt on it when I pull it to clean it every month as the normal home filters do. I have to assume it isn’t catching as much dirt just like their automotive filters. Also the external dimensions of the filter made it not fit tight into the filter housing. Another thing is unless you have 2 when you take it out to wash it, until it’s dry your unit will be running without a filter and they take forever to dry if it’s not 100 degrees outside.

I’m going back to regular filters even though I hate constantly adding to the landfills with them.

Just don't run the sticker I'm still waiting on a contingency check from last July they want their signage all over NHRA events and they are one of the worst paying companies.

I stear away from using high merv air filters in my home.

Not a fan of K&N products

I've done some research since posting & most of what everyone has posted. Have shown up in the reviews, mixed opinions. Guess I'll just have to try them out.

Just like most things in life, air filtration is a trade-off. It's easy to get sold on, and want to, filter that last micron. However the more restrictive a filter the harder the furnace/AC has to work to achieve a given temperature. Basically you have to find what fits you the best between addition run time vs. cleanliness of air and the expense and wear and tear on your system. Which means a shorter life/quicker replacement cost. The asthmatic would likely lean towards a tighter filter, whereas the average person, planning on living in his house for a long time might lean toward conservation of equipment.

I have dual returns on my unit. One 14x24 and one 14x14. Best of both worlds I guess.

Most HVAC guys will tell you to not run the high merv. If the unit is designed for it, then it is a good thing.

K&N is supposed to have a MERV of 11.

I didn't know K&N made HVAC filters until seeing this post.
I alternate filter ratings, depending on season. My son and his mother get allergies in Spring and Fall, so I use slightly tighter filters during those seasons, since the temps are mild and the HVAC system duty cycle is very low, (short run times, and not frequent), so it isn't really doing much harm. The peak demand seasons are Summer and Winter, heavy duty cycle rates, and lower pollen rates, so I use the lower MERV, looser filters which are not only easier on the equipment, they actually give better heating and cooling performance due to the higher airflow.

Any and all regardless of brand, high MERV filters will make your home dusty. Really can't go wrong with "el cheapo" blue old school furnace filters from my experience.

I would think it would be the opposite? I thought higher MERV is better filtration. I know any pleated paper element is probably better at reducing dust than the old school open weave filters that really just protect the blower from large moths or rodents, and not much else?

I thought the exact same thing but i found out much differently after a couple years of running the higher MERV pleated filters. They choke down the CFM so much, the dust moves around the house but doesn't make it to the filter (or at least it seems less of it does)... so when you do change them out, they look cleaner and that is why from my experience. Those thick filters are one of the fastest ways to kill a compressor.

I suppose that makes sense, I can definitely tell the difference in air movement in our house when I put the less restrictive filters in...

For anyone that might prefer running the old angle hair filter I would recommend this product. Kind of like oiling a K&N for your house.

Good morning all.
As a general rule, most home A/C/heating units work very well with a Merv 8/10 pleated filter.
These filters will trap 40% of all particles .03 micron and larger. As the filter gets dirty it will start to capture a higher % of particles.
Generally these filters will need to be changed out every 3 months. In some newer modern homes this could go to every 4 months.
Not a big fan of washable type filters, they really need to be cleaned often and do require you getting 2 of them as you do not want to put a wet filter back in the unit.
Just my 2 cents worth.
Have a GREAT DAY!!!
