“Finding the right filter can be confusing. That's why we're here to offer honest advice and the best products, so you can breathe easy knowing you made the right choice for your family.”
Shop by Filter Size - Standard and Custom
From common sizes like 16x25x1 to hard-to-find dimensions, we have the exact size you need. If you don’t see your size, we can build a custom filter just for you.
Shop by Filter Type - Find Your Match
Choosing the right filter material is the first step to cleaner air. Each type offers a different level of filtration to match your needs and budget.
- For Basic Equipment Protection: Fiberglass filters offer maximum airflow and protect your HVAC system from large dust and lint particles.
- For Cleaner Residential Air: Pleated filters are the most popular choice for homes, capturing smaller particles like pollen, pet dander, and mold spores.
- For Odor and VOC Reduction: Carbon-infused filters absorb smells from pets, cooking, and smoke, plus remove volatile organic compounds (VOCs).
Shop by MERV Rating - Control Your Air Quality
MERV (Minimum Efficiency Reporting Value) measures how effectively a filter captures airborne particles. A higher MERV rating means cleaner air, but it’s important to choose a rating your system can handle.
MERV 3-6: Good for basic protection and commercial spaces where airflow is key.
MERV 8: The industry standard for homes. A great balance of filtration and airflow.
MERV 10-11: Ideal for pet owners and people with mild allergies.
MERV 13: Maximum residential filtration for superior air quality. (Consult your HVAC technician before using).
