Best Furnace Filters: Choosing a Furnace Filter

Heating and cooling systems are important in keeping your home warm in winter and cool in the heat of summer. A furnace filter is a just small part of this entity, but it keeps it humming in peak performance.

When the system has a dirty air filter, it will not work effectively, and it can even lead to a breakdown.

How are Furnace Filters Rated?

Furnace filters are compared using MERV (Minimum Efficiency Reporting Value) this is a rating that provides a standard comparison from 1-16. A high rating indicates a high efficiency of that particular furnace filter.

Most homes will have a furnace filter with a rating between 8 and 12. This is the most common as it covers a wide range of particles.

Here’s a look at the rating and what it means the filter can handle

• 1-4- this rating covers dust mite, pollen, sanding dust, spray paint, dust, textile fibers, and carpet fibers. These are large particles, meaning they will provide minimal filtration. These furnace filters can be used for both residential and commercial buildings, and their work is to ensure the HVAC system is running correctly but not improve air quality.
• 5-8- this rating goes for mold, spores, hair spray, fabric protectors, dusting aids, and cement dust. These filters are used in commercial buildings, industrial workplaces, paint booths, and also residential properties.
• 9-12- this rating is for smaller particles like Legionella bacteria, humidifier dust, lead dust, milled flour, auto emissions, and welding fumes. They provide superior residential filtration along with better filtration for commercial buildings and hospital laboratories.
• 13-16- this rating indicates the filter can capture all bacteria, most tobacco smoke, and droplet nuclei. These filters provide great performance in general surgery, hospital inpatient care, smoking lounges, and also give superior air filtration for commercial buildings.

MPR

This refers to the Micro-Particle Performance Rating. It was developed by 3M and measures the capability of furnace filters to capture particles less than 1 micron from MRM300-2800. Filters with a rating from 1500 to 1900 are considered the most effective in a wide array of environments.

HEPA

High-efficiency particulate air (HEPA) provide an electrostatic filter that can trap up to 99% of particles of the size 0.3 microns or larger. They are excellent at trapping air pollutants, but they can reduce your system’s airflow to drastic levels which may lead to increased energy charges.

FPR

Developed by home depot, this is a filter performance rating on a scale of 1-10. A high number indicates a better filter.

Types of Furnace Filters

Disposable Pleated Filters

This kind has a construction of paper and polyester. They are a standard for most household allergens and particles. The materials are affordable and environmentally friendly. These filters require frequent changing to prevent clogging the HVAC system.

Disposable fiberglass

These filters are also very common. They provide filtration of large particles like lint; thus preventing clogging of the system. They do not do much more like improving the air quality.

Disposable Electrostatic

These filters charge as air is let through them. They are made from cotton fibers or paper fibers. They are great for homes with pets or for people who smoke inside since they can capture small particles.

Permanent Electrostatic

These are washable and reusable filters made from aluminum or plastic frames. They carry the washable filters in the frame, and they can also be vacuumed. These filters can be used for up to 8 years before they need replacing.

Highly Efficient Pleated Filters

Instead of the regular 1-inch designs, highly-efficient pleated fibers are 4-5 inches thick. They can filter the smallest particles. They usually have a high MERV rating and can last up to 12 months before being replaced.

How to Choose by Size?

Filters mostly come in 1-inch sizes, but you will also find 4 and 5-inches thick filters. Filters are also sized by the length and height. It’s essential that you know the right size for your system.

Simply check the size on the back of your current filter when you remove it.
