In this regard, what is the best MERV rating for furnace filters?

A MERV rating between eight and 11 is adequate for most homes. To be safe, you should check if your furnace manufacturer has a maximum MERV rating your model of furnace can use.

Additionally, are cheap furnace filters better? Cheap fiberglass filters are designed to stop dust, debris and hair from gunking up the system. They are also pricier than basic fiberglass filters. 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.

People also ask, is there a difference in furnace filters?

More expensive (electrostatic) furnace filters capture smaller particles and need less changing than cheaper (pleated) and the cheapest (woven fiberglass) filters. If you have allergies, consider electrostatic filters. Instant!

Are thick furnace filters better?

Filter thickness: A filter's thickness can range from 1″ to 5″. As a general rule of thumb, a thicker furnace filter will last longer and can be more efficient. Your system configuration will determine the thickness of the filter that you can use.

What MERV rating should I get for home?

The MERV rating scale ranges from 1-16. Lower quality filters, in the 1-4 MERV range, are typically made of fiberglass. Most residential HVAC systems will use air filters with MERV ratings from 7-12. A higher MERV value of 5-16 would be recommended for commercial buildings.

What happens if furnace filter is backwards?

By installing your filter backwards, air will have a harder time flowing through the filter and your air handler will have to work harder to make up for the loss of airflow. That arrow must always face toward the furnace and away from the return duct that carries the air in need of heating or cooling.

Does MERV 11 restrict airflow?

A decade ago, it used to be that if you had an HVAC system that used panel filters rated 6 through 9 MERV, putting in a MERV 11 or higher filter would restrict airflow (known as filter pressure drop). In turn, this would lengthen the system's run-time, adding to your heating and cooling costs.

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.

Will MERV 11 hurt my furnace?

Keep in mind that a MERV rating higher than 13 could negatively affect some HVAC systems, so it is advisable to verify that your unit can handle a higher rating before you make your purchase. According to Alex Hertzog, our in-house air filtration expert, MERV 11 filters are recommended.

Are expensive air filters worth it?

More expensive filters like Pleated Residential filters filter out dust mites, pollen, mold and pet dander and even bacteria and so are worth the money especially for those with severe allergies. HEPA filters filter bacteria and viruses and are worth the extra money for those with respiratory conditions like emphysema.

Why does my air filter get dirty so fast?

When your A/C is on the thermostat fan will constantly be running causing air too run over the air filter continuously and causing it to get dirty more quickly. You may have a leak in your air ducts - Leaky air ducts can also cause your filter to clog up and especially if it is near your AC unit.

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.

Why are furnace filters so expensive?

The more expensive filters make people feel good they are doing all they can to make their house clean so big box stores sell them. If the fan is run 24/7 and there are no leaks around the filter due to a poorly fitting filter rack then a more expensive filter may do a very slightly better job.

Do Filtrete filters restrict airflow?

Because they restrict airflow to your HVAC system. Pleated, high-MERV filters definitely capture a lot of pollutants, but they also restrict the movement of air into your blower or furnace. These cover all the air filtration basics - dust and pollen removal, for example - without restricting airflow.

Is there an air filter in the furnace?

In general the furnace filter is located inside the blower compartment. This will vary with the installation of the Furnace. The HVAC (Heating Ventilating and Air Conditioning) contractor can install an Air Cleaner Box, or cut a slot in the return air duct.

Furnace filters are sized by width, length and thickness. The size on the filter is usually expressed in inches (example: 16"x20"x1").

Pleated air filters might also require you to modify your HVAC system in order to accommodate them. Ultimately, they are typically 3 times more costly than traditional non-pleated filters.

What MERV rating can my furnace handle?

For most residential home's furnaces and air conditioning units the recommended MERV rating is between a MERV 8 and 12.
