Is MERV 8 better than MERV 11?
Because it can pick up smaller particles than a MERV 8, a MERV 11 filter will make their lives easier. We recommend that you have a MERV11 air filter for those with health issues, especially in the spring and summer.
What MERV rating is the best for home use?
Higher MERV ratings for residential filters (5-8) will remove common allergens in the home such as pollen, dust, and pet dander. However, superior residential filters (9-12) will remove cigarette smoke which is more difficult to filter due to its smaller particles.
Second, is MERV13 better than MERV11? The MERV ratings range from 1 (low efficiency, minimum filtration) up to 20 (highest efficiency, highest filtration). The MERV13 filters will suffice for most household needs. FiltersFast's MERV 11 filters are the best choice for your home.
Is MERV 11 a restriction on airflow?
A decade ago, HVAC systems that had panel filters rated 6-9 MERV were advised to install MERV 11 or greater filters. This would reduce airflow, also known as the filter pressure drop. This would increase the system's lifespan and cost you more in cooling and heating.
Is MERV 11 excessive?
High-efficiency filters with MERV 11-13 are available in many configurations. These filters can remove particles as small and as large as 0.3 microns, as well as other debris such as bacteria and microorganisms.

Is MERV 8 good enough?
MERV 5–8 (good): These filters are better at catching small particles (3–10 microns) like mold spores, hair spray, dust mites and animal dander. MERV 13–16 (best): These filters are usually only found in hospitals because they can capture particles as small as 1–0.03 microns in size.
Is MERV 13 too restrictive?
MERV is a good way to help judge the effectiveness of an air filter. In some cases, using an air filter that is too restrictive for your system may cause low air flow problems as well. MERV 13 is the highest MERV value safe for residential furnaces; the higher ratings are used primarily in commercial units.

What Merv furnace filter should I use?
Furnace filters are rated using the minimum efficiency reporting value (MERV). MERV ratings range from 1 to 16. Higher rated filters allow less air to flow through though and can force your furnace to work harder and possibly malfunction. A MERV rating between eight and 11 is adequate for most homes.
Are expensive air conditioning filters worth it?

Which furnace filter should I buy?
Choosing the right furnace air filters for your furnace
The minimum efficiency reporting value (MERV) scale goes from 1 to 16. Furnace manufacturers prefer the traditional spun fiberglass ac filters (MERV 2). These filter out enough of the large particles to protect the furnace while providing maximum airflow.How often should you change your furnace filter?
every 90 days
Which way is airflow on AC filter?
On your new air filter, find the arrow that indicates the proper air flow direction. This tends to confuse everyone more than anything else. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.
Can I use a thinner furnace filter?
If you have a forced-air furnace, it uses a filter. The thinner filters need to be changed every month or so. What size of filter you can use in your furnace depends on the size of the slot. You may be tempted to use a filter that's not as thick as the slot.
Do higher MERV filters restrict airflow?
Because high MERV filters are designed to catch large and small particles and therefore will get dirty quickly. And since the filter is thin, the filter will quickly fill up with particles and block airflow.
Are cheap furnace filters better?
Cheap fiberglass filters are designed to stop dust, debris and hair from gunking up the system. While pleated filters will do a better job of cleaning the air than fiberglass, there are better options to clean the air efficiently without adding stress to the system.
Can I put filters on my air vents?
Do not put filters in your supply vents. Your AC system should have a proper fitting filter on the return side. By placing a good fitting, high quality filter on the return vent, you will remove particles from the air before they can enter the AC system.
