How to Choose the Best Air Filters for Your Home AC

Choosing the best air filters for your home AC depends on your preferences and comfort zones. Here is a guide to discovering the most suitable home air filter for you.

Introduction:

Air filters are the essential parts of HVAC units that should not be left unattended. Nonfunctional and damaged air filters are likely to allow harmful bacteria and other particles to enter your home. Additionally, the blockage will restrict the air conditioning system to maintain airflow and produce cold air at the desired temperature. Blocked air filters will eventually impact the integral parts of the air conditioner units.

At times, certain damages can be beyond repair, and the only option you might have is air conditioner filter replacement. Replacing air conditioner units can add more life to your air conditioning unit and boost its efficiency to the next level.

But, finding the best air filters for home AC can be quite challenging, especially if there are several options to choose from. If you are having a troublesome time finding the best home air filters, you happen to be in the right place.

Before you finalize your purchase decisions, here is everything you need to know about different types of air filters for your home.

What do you need to know before buying air filters?

Considering these below-mentioned pointers will help you make the right purchase decision and discover suitable air filters for your home.

1. Filter type

It is important to understand that not all air filters are created equally. Depending on the dimension, model and usage of conditioning units, air conditioner filter sizes can differ from one model to another. Here are the different types of air filters to choose from.

  • Pleated or fiberglass filters

    Fiberglass filters are one of the best air conditioner filters for houses as they are more affordable and readily available than other options. Pleated air filters are less porous and can catch more airborne pollutants or allergens than fiberglass filters.

  • Disposable air filters

    Unlike other washable or reusable filters, disposable filters are disposed of once used. Disposable air filters are considered the best air conditioner filters for houses as they can easily trap smoke, bacteria, and pet danger.

  • Washable air filters

    Compared to disposable filters, washable air filters have less potential of catching minor dust particles, bacteria, and pet dander. It is advisable to opt for other options for better air quality in your home.

2. HEPA-type air filters

HEPA-type air filters are undoubtedly one of the best air filters suitable for places with low air quality and have a higher risk of being exposed to bacteria and airborne particles. HEPA-type air filters can be more costly than other options. If the price is not your primary concern, consider opting for HEPA-type air filters. However, read the instructions and manufacturer's specifications carefully before purchasing this filter.

3. MERV ratings

The minimum efficiency reporting value (MERV) ratings signify the air filter efficiencies. The best air filters always have high values and trap large amounts of bacteria and other particles. Air filters ranging between 1-6 MERV rating can trap particles with 10.0-micron sizes, such as pollen, dust mites, carpet fibers, and more. Air filters ranging between 8-13 MERV can trap particles 3.0-10.0 microns, including fumes, smoke, mold, dust, smog, and more. Lastly, air filter MERV ratings ranging from 14-20 can trap particles as small as 0.30 microns, such as radioactive and carcinogenic particles.

4. Health problems

If you or your family members face breathing problems like asthma, you should opt for the highest and the best air filter quality in the market. Consider opting for air filters having a MERV rating between 10-20 for a better air quality experience.

5. Replacement duration

The air conditioner filter replacement duration may vary depending on the air conditioner filter sizes and other variables. Always check the size, shape, and other factors of your AC units before purchasing a different company’s or brand’s air filter for your home. Get in touch with us to discover the best type of air conditioner filter for your AC units.

6. Price

If you opt for defusable air filters, avoid purchasing expensive filters. No matter how costly defusable filters are, you have to throw them away once their efficacy limits exceed. Hence, it is advisable to opt for the best home air filters at affordable prices. Discover a wide range of high-quality, functional, and cost-effective air filters at Penn Tool Co.
