HVAC Air Filters in Ogden, UT
Emphasis on clean IAQ (indoor air quality) is not a trend; it’s a way to live healthier, more comfortable lives. If you share your home with infants, seniors, or family members who are in treatment for illness, clean air circulation can make a big difference to their health.
Clean air in Northern Utah makes life better for all of us.
We’re spending much more time in our homes, and the EPA says our indoor air is significantly more toxic than outdoor air. Airborne allergens and pollutants can be controlled with high-efficiency HVAC air filters.
How Do HVAC Air Filters Work?
Air cleaners and HVAC filters are designed to filter pollutants or contaminants out of the air that passes thru them. Air cleaning and filtration can help reduce airborne contaminants, including particles containing viruses. — EPA.gov
Our heating and cooling systems use HVAC filters to trap airborne pollutants, such as:
- Carbon monoxide
- Excess moisture
- Pet dander
- VOCs (volatile organic compounds)
- Aerosol sprays/paints
- Air fresheners
Your HVAC air filter confines these contaminants and prevents them from recirculating in your home.
You may have heard about MERV (minimum efficiency reporting value). The MERV rating is a filter’s ability to capture small (0.3 microns) to larger (10+ microns) pollutants. A higher rating means a higher resistance, but it also means less airflow can pass through the filter.
For example, the lowest MERV rating is 1–4. It will filter dust and textile fiber. But a MERV rating of 17–20 could block your HVAC system’s airflow, causing problems. A 13–16 is considered “hospital” quality filtration and can be used in homes, but you may see better system efficiency at a lower MERV rating, like 7–13.
Types of HVAC Air Filters
There are four types of HVAC air filters:
- Flat-paneled fiberglass: These disposable filters have layers of fiberglass and metal-reinforcing lattices. They’re the least expensive and have a low MERV rating. This means they’re effective in filtering larger particles, but they don’t trap small ones as well.
- HEPA: High-efficiency particulate air filters are the best. They can trap small-particle pollutants, including cigarette smoke. HEPA is the highest rated but it can also impede airflow, so the filter must be carefully selected.
- Pleated media: These have a higher MERV than flat panels. They are affordable and more efficient than most washable filters.
- Reusable: Washable, reusable filters cost more and aren’t usually the best for air filtration. If you have indoor pets or smokers, you should not use them.
Benefits of High-Efficiency HVAC Air Filters
High-efficiency air filters can stop airborne irritants and even bacteria that cause contagious viruses.
Finding a careful filtration balance — a MERV rating that works best — is residence-specific. Your Northern Utah HVAC professionals at Mountain Air have the expertise to know exactly what will work best with your heating and cooling system.

Frequently Asked Questions
Does changing the HVAC air filter improve performance?
Replacing your HVAC air filter will significantly improve performance and efficiency because the system needs to work harder to pull air through a filter thick with dirt and other debris.
If you’re using HEPA filters or other similarly dense filters for even cleaner air, it becomes even more important to replace your filters regularly, as this type of filter can end up completely blocking intake when dirty — which will lead to little or no airflow, freezing evaporator coils on air conditioners, damage to internal components due to overheating, and more.
Regularly replacing your air filters should be a high priority for immediate comfort, air quality, and the reliability and long service life of your system.
How long do air filters last before they need to be replaced?
It’s generally recommended to replace your air filters monthly, but there are countless factors in the final determination. The higher the filtration rating of your air filter, the sooner it will become clogged because it catches more of the debris that attempts to pass through it.
There’s also the consideration that every house has different amounts of air pollution a filter might catch; houses with pets, old homes with dust or mold problems, places with tons of pollen, and such will naturally end up dirtying their filters sooner than other homes.
This assumes you have replaceable filters, of course, and not washable filters. It’s best to start based on manufacturer recommendations and adjust from there if you notice your filters are exceptionally dirty by the time you replace them.
