Filter Information

Breathe Cleaner, Healthier Air with Certified Filtration

Most Americans spend up to 90% of their time indoors, yet few realize that indoor air can be 2 to 5 times more polluted than outdoor air (EPA). From allergens and pet dander to smoke, bacteria, and volatile organic compounds (VOCs), many of these pollutants are invisible—and continue to recirculate unless effectively captured by high-quality HVAC filters.

The Problem with Poor Indoor Air Quality

What you see in a beam of sunlight—dust and floating particles—is only a fraction of the airborne pollutants present in your home or office. Many harmful particulates are too small to see, yet they can trigger asthma, allergies, and other respiratory issues. These include:

  • Fine dust and lint

  • Pet dander

  • Pollen

  • Mold spores

  • Bacteria and virus-carrying particles

  • Odors and smoke particles

Why Choose Accumulair and Arm & Hammer™ Filters?

At Filter Market, we specialize in high-performance air filtration products from two trusted brands: Accumulair and Arm & Hammer™. These filters are rigorously engineered to meet or exceed ASHRAE Standard 52.2, using advanced materials like:

  • Electrostatically charged pleated media to capture microscopic particles

  • Odor-neutralizing carbon (Arm & Hammer™) to reduce VOCs, pet smells, and smoke

  • Moisture-resistant frames and media that do not support microbial growth under normal HVAC use

What Is MERV and Why Does It Matter?

MERV (Minimum Efficiency Reporting Value) is the industry-standard scale developed by ASHRAE to measure a filter’s ability to capture particles in 3 size categories:

MERV  Particle Size Range Captured Common Pollutants
MERV 8 ≥3.0 microns Dust, pollen, lint
MERV 10–11 ≥1.0 microns Pet dander, mold spores
MERV 13 ≥0.3 microns Smoke, bacteria, fine dust, virus carriers

Higher MERV = finer filtration. Both Accumulair and Arm & Hammer filters are available in MERV 8, 10, 11, and 13, so you can match the filter to your home's air quality needs and HVAC compatibility.

Disposable vs. Washable Filters

Reusable and fiberglass filters typically range from MERV 4 to MERV 6, offering minimal protection against airborne threats. In contrast, disposable pleated filters:

  • Provide higher-efficiency filtration

  • Do not require time-consuming cleaning

  • Do not support mold growth when used as directed

  • Maintain structure and airflow integrity over time

In fact, washable filters that aren’t fully dried before reinstallation may become breeding grounds for mold or bacteria, compromising indoor air rather than improving it.

Why You Should Replace Your Filter Every 3 Months

Clogged filters reduce HVAC efficiency and allow more pollutants to bypass into your home. Replacing your filter every 90 days (or more often in homes with pets, smokers, or allergy sufferers) helps:

  • Maintain system performance

  • Improve energy efficiency

  • Enhance indoor air quality

  • Extend HVAC unit lifespan
