Are You Confused About MERV Ratings? The options may seem daunting at first—with different filter types and various MERV ratings, but don’t worry because we’ve made it easy. 
Does Airflow Matter?
The higher the MERV rating, the more efficient the filter is at catching small particles. However, it reduces the amount of air that can pass through the filter.
Imagine breathing through a face mask—it can be difficult at times. Now, double or triple the thickness of the mask and it becomes extremely difficult, requiring far more effort to take in air. Well, that is exactly how works with HVAC systems. They are designed to accommodate a certain amount of resistance—or static pressure—and if you increase that too much, the system will struggle to operate.
The best air filter is one that captures most contaminants but allows air to flow freely. That is why the Zephyr Filtration MERV 13 air filter is the optimum choice for replacement return air grill filters. Its low static pressure means that air passes through easily while collecting the spores and aerosols that can lead to sickness.
Are Your Home Air Filters Restricting Airflow? Indoor air quality can be ruined by the filters in your home, and it’s important to know how they affect airflow. A dirty or inefficient filter will reduce circulation while overly efficient ones might actually cause more problems than they solve—like over heating! You can learn more here →
The Zephyr Filtration MERV 13 Air Filter
For HVAC contractors, the Zephyr Filtration MERV 13 air filter provides solutions to many of the problems faced when replacing filters or installing new systems.
- Low static pressure equals zero strain on the system.
- It fits most standard 1” thick air return grilles, eliminating the need for expensive modifications.
- It’s long-lasting (six months or more) reducing the frequency of callouts. This follows biannual preventive maintenance schedules.
- The adhesive faced foam gasket provides a complete seal to ensure all the air goes through the filter, not around the sides.
The California Building Energy Efficiency Standards were introduced to ensure new and existing buildings achieve a good energy efficiency rating. The Zephyr Filtration MERV 13 air filter is fully compliant with Title 24, making it the top choice among professionals.
Frequently Asked Questions
The short answer is that you can usually use a MERV 13 filter in your home. However, it will depend on the condition and performance of any existing HVAC system. If filtration is already a struggle due to an old and/or poorly functioning unit, then purchasing high-grade filters may not help resolve these issues. So, before purchasing or installing any new filters be sure to consult a local IAQ expert. Find a Local Professional →
The short answer is that it can, but high-efficiency air filters are still a much better option for your HVAC system. MERV 13+ air filters work with most modern systems without any issues or problems under normal circumstances. If you notice any change in performance after installation, like decreased airflow or the system keeps shutting off, stop use immediately and consult a local professional.
