Furnace Filters – Buyer’s Guide

MERV

MERV is used domestically and internationally as the industry’s premier rating system. Established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers, MERV assesses a filter’s ability to capture and retain particulates and pollutants. Higher MERV-rated filters can capture and remove smaller particles.

MPR

Developed by 3M, Micro-Particle Performance Rating, or MPR, is a rating system that sets manufacturers’ filters for the efficiency of capturing airborne particles less than 1 micron. Filters are classified only by their ability to remove particles from 0.3 to 1 micron. A good example is this, a typical dust particle ranges from .2 and 8 microns, pollen starts at 7 microns but can be up to 70 microns in size.

FPR

Filter performance rating, or FPR, labels filters based on a scale of 4 to 10 plus a color-coding system. This system was designed by Home Depot.

MATERIAL

Pleated furnace filters are more efficient and durable than fiberglass non-pleated filters. Pleated filters have more surface area allowing them to capture more contaminants/contaminants. They also have smaller pores that trap smaller particles without disrupting the airflow.

THICKNESS

Filters have a thickness ranging from 1″ to 5″. A thicker furnace filter lasts longer and is more efficient than thin filters. The thickness of your filter is determined by the configuration of your system.

FAQs

What are the Different Types of Furnace Filters?

There are four types of furnace filters, the first and least expensive are fiberglass filters. These filters are disposable and not as durable compared to the other types. Fiberglass filters are not an ideal choice for households where people with allergies live. This is because these filters usually have a low MERV value of 4. However, they put less strain on your HVAC system than others, giving you more airflow.

The second and most budget-friendly are pleated filters. These air filters are made of cotton or polyester pleats. They cost slightly more than fiberglass filters but are more effective at filtering out dust and other small particles such as mold spores, pollen, and pet dander. Filters with more pleats provide better filtration that helps prevent dust and other particles from being recirculated. They usually have a MERV value between 5 and 8.

HEPA filters are the 3rd type, which is the best possibility for people who have allergies or respiratory problems. These filters cost more than those of fiberglass and pleated but offer the most effective filtering. HEPA filters 99.97% of dust, pollen, mold, pet dander, viruses, bacteria, and other airborne irritants. Filters with a MERV value of 11 or higher are best. Keep in mind that the higher the MERV value, the harder it is for your HVAC system to pull air through it. Check which MERV rating best suits your system.

How long do oven filters last?

The durability of a filter is restricted by its thickness. A 3- to 4-inch filter will last six to nine months. Thicker filters from five to six inches will last nine to 12 months.

When should you replace your oven filters?

Here’s a general rule for replacing your HVAC system’s air filters. Replace 1-2 inch filters every 3 months, 4-inch filters every 6 months, and 5-inch filters every 12 months.

What problems can arise without an oven filter?

Without an air filter, the HVAC system spreads pollutants throughout your home, resulting in poor indoor quality. Health experts have found that exposure to these pollutants can lead to health problems such as asthma and other respiratory problems.
