MERV Ratings

MERV stands for Minimum Efficiency Reporting Value. MERV Ratings vary between 1 and 16. As the rating increases, the fewer the number of particles that will be able to pass through the filter media.

Filters with higher ratings may not be the right choice. A filter with a high Merv rating may force your furnace to work harder, become less efficient and cost more to operate. A merv rating between 8 and 11 is sufficient for most homes. To be on the safe side, check with your furnace manufacturer or service technician in Canada to determine the best furnace filter for your system.


Five types of filters commonly used in our Canadian homes.

High Efficiency Pleated

Generally chosen by most homeowners. They are available in an array of sizes, as well as merv ratings. Pleated filters are made with synthetic material, eliminating moisture buildup and the growth of mould. They perform very well, filtering out household allergens and particles. The pleats are evenly spaced to provide efficient airflow. The pleat material is fixed to a rigid grid to keep the pleats in place and provide good durability. The price of pleated filters varies, depending on size, brand and rating.They should be checked monthly for any blockages and replaced every 90 days. They are economical and can be manufactured from green materials. A good choice for those who have respiratory problems or looking for overall improved indoor air.

Standard Fiberglass

These are the least expensive filters available. They have a "spider-web" like appearance and are typically blue in color. Available in an array of standard sizes and are more delicate, as well as having a lower merv rating than pleated filters. These disposable filters must be frequently checked and often need to be changed monthly.

Washable

Washable filters are made with either a plastic, or aluminium frame. They can be vacuumed and cleaned with water. Available in a multiple of sizes, as well as different merv ratings. They're more expensive, but can last up to five years, which would make them a good economical solution. Proper maintenance is required and they should be cleaned every 90 days.

Disposable Electrostatic

This type of filter has electrically charged fibers that catch contaminants as they pass through the media. Good for homes that have pets or tobacco smoke. Check your furnace manual to make sure that your system is suitable to operate electrostatic filters safely.

Permanent Electrostatic

These filters have self charging cotton fibers that attract particles. They have a detachable, machine washable filter that can be re-used for up to 8 years.

Common furnace filter sizes in Canada and USA

Furnace filters are sized, based on depth (thickness), length and height. The most prevalent thickness is around 1", with 4" also serving as a popular choice. Length and height combos range from 10x10 inches to 30x30 inches. The most common available sizes are 14x20x1 , 16x20x1 , 20x20x216x25x1 , 16x25x5 and 16x25x4.

To determine the size of your furnace filter, remove and examine the existing one to be replaced, or refer to your furnace manual.

FREQUENTLY ASKED QUESTIONS

What is the primary purpose of an air filter?

The primary purpose of an air filter is to remove contaminants such as dust, pollen, mold spores, and other airborne particles from the air passing through it. This helps improve indoor air quality and protect HVAC system components from dust buildup.

How often should I change my air filter?

The frequency of air filter replacement depends on several factors, such as filter type, indoor air quality, household size, and whether you have pets. In general, it is recommended to replace standard 1-inch filters every 1 to 3 months. High-efficiency filters may last longer, up to 6 to 12 months.

Are high-efficiency air filters worth it?

High-efficiency air filters, such as HEPA filters, can remove smaller particles and allergens. They are worth it if you or your family members suffer from allergies, asthma, or respiratory issues. However, they can also put additional strain on HVAC systems not designed for them.

Can a dirty air filter affect my HVAC system's performance?

Yes, a dirty or clogged air filter can reduce airflow, forcing the HVAC system to work harder. This can lead to reduced efficiency, higher energy bills, and potential damage to the system over time.

What's the difference between MERV and HEPA filters?

MERV (Minimum Efficiency Reporting Value) is a rating system for air filters that ranges from 1 to 16. Higher MERV ratings indicate better filtration. HEPA (High-Efficiency Particulate Air) filters are a specific type of high-efficiency filter that can capture at least 99.97% of particles as small as 0.3 microns.

Do air filters help with odors?

Some air filters are designed to help with odors by incorporating activated carbon layers that absorb volatile organic compounds (VOCs) and other odor-causing particles. Standard particulate filters generally won't address odors.

How do I choose the right air filter for my home?

A: To choose the right air filter, consider factors such as the size of the filter required by your HVAC system, desired MERV rating, any specific allergies or health concerns, and whether odor control is important. Also, ensure that the filter won't overly restrict airflow for your HVAC system.
