How to Choose the Best Air Filter

Off By

There are many factors to consider when purchasing an air filter for home. These include MERV rating, the grade of the filter, and the material of the filter. For residential use, MERV 6-8 filters are the most common, and they are made of pleated cloth or paper for greater surface area to trap particles. MERV 9-12 filters are the middle of the road in filtration quality and can capture very small particles. MERV 13-16 filters are the best of the standard filters. These filters can be made from cotton gauze, stainless-steel mesh, or paper.

MERV rating

MERV ratings measure how effective a filter is at removing dust particles. They can range from 1 to 20. The higher the rating, the better the filter. The lowest MERV rating can only filter small amounts of dust. A higher MERV rating will give you better results. A filter with a MERV rating less than four indicates that it is not efficient. If you’re concerned about the cost of a higher MERV rating, consider using a lower MERV rating.


Air filters come in many grades. You should make sure you buy the correct one. It could cause damage to your HVAC system. The pleated filters are 20 times more efficient that fiberglass filters. MERV, or Minimum Efficiency Reporting Value, is the system used to rate air filters. MERV indicates how large particles can pass though an air filter. The American Society of Heating, Refrigeration, and Air Conditioning Engineers developed the standards and also created the MERV rating.

Stainless steel mesh

An air filter made of stainless steel mesh is durable and reliable for ventilating systems. These filters can filter all air that passes through them and still function as an appliance’s normal functions. Stainless-steel mesh filters are generally metal disc-shaped and can be ordered in a range of sizes to fit any application. Zoonsteel produces a large number of these filters. They can help phase out dust and other air contaminants in a variety of applications.

Cotton gauze

If you’re planning to replace your current paper air filter in your car, you should consider purchasing a cotton-based model instead. These air filters are more effective and convenient, and they’ll last the life of your car. Cotton filters contain oil to help trap dirt and other muck in the air. These air filters feature pleated cotton fibres interwoven with metal meshing. Although cotton-based air filters tend to be more expensive than paper filters, their higher flow capacity makes them an excellent investment.


If your current foam air filter needs to be cleaned, it is important to do it right the first time. Use of harsh chemicals to damage foam structures and reduce their life expectancy can be detrimental. Use a mild solvent such mineral spirits to clean your foam-air filter. An auto parts store may also sell solvents with high flash points. To catch solvents, make sure to strain them and then reuse them. This will not only extend the life of your foam air filter, but also make it easier to clean.

An air filter’s resistance is its ability to remove larger particles and standard dust from the airstream. These larger particles include hair, lint and dust. When a filter is compared to how much standard dust it can hold, its resistance value is equal to its holding power. There are three types of resistance ratings available for air filters: medium, high, and low. Low-resistance filtration has resistance values of 0.18 inches/square meter. Medium-resistance filters resist 0.500-inches/square inch. High-resistance filters have a higher capacity to hold larger particles than low-resistance ones. They are generally rated at one-inch/square foot.


MPPS is the largest size particle that can penetrate a respirator. Generally, the pore size ranges from 0.05mm to 1.5mm. But, depending on the filters parameters, it may be smaller or larger. Despite its name, the pore size doesn’t determine particle capture. Instead, it happens through diffusion, imaction, and settlement.

ASHRAE arrestance

The most widely used standard to determine the performance of an Air Filter is the ASHRAE arrestance test. This test measures particle counts upstream and downstream over a wide range of particle sizes. The particle size range is listed in Table 1. The test also uses a generator to produce particles of known sizes in the air stream. The test should be repeated at least six times to get an accurate estimation of the air filter’s arrestance percentage.
