FAQs
What does the MERV rating on a media filter mean, and why is a higher number better for Rockford homes?
MERV (Minimum Efficiency Reporting Value) is a 1–16 scale that measures how effectively an air filter captures particles between 0.3 and 10 microns. A standard 1″ throw-away filter is usually MERV 1-4 and only traps the largest dust. High-MERV media filters (MERV 11-16) are pleated and 4–5″ thick, allowing them to catch much smaller contaminants such as pollen, mold spores, pet dander, and even some bacteria and viruses. Rockford residents benefit from higher MERV filters because our area sees heavy spring pollen, agricultural dust, and long winter seasons when windows stay closed and indoor air gets stale.
Will a high-MERV media filter hurt the airflow or damage my HVAC equipment?
Not when the filter is properly matched to your system. Modern 4–5″ deep media filters have many more pleats than a 1″ filter, so the total surface area is larger and static pressure stays within manufacturer specs. Before installing a MERV 13-16 filter, we measure the existing external static pressure and verify blower capacity. If needed, we can upgrade fan speed settings or the blower motor. The result is cleaner air with no appreciable loss in airflow or comfort—and usually no measurable increase in energy costs.
Can I add a high-MERV media filter to my current furnace or air handler, or will I need new equipment?
Most systems in Rockford can be retrofitted. We replace the 1″ filter rack with a 4–5″ media cabinet that slides into the return plenum. The service typically takes one visit and does not require replacing the furnace or ductwork. In rare cases—older low-capacity blowers, undersized return ducts, or a rooftop unit with limited clearance—we’ll discuss modifications or other filtration options (e.g., an electronic air cleaner). A no-cost in-home evaluation lets us confirm compatibility before you commit.
How often should a high-MERV media filter be replaced around Rockford, and what factors shorten its life?
A 4–5″ MERV 11-13 filter generally lasts 6–9 months; MERV 16 may need changing every 4–6 months. The exact interval depends on: 1) runtime (long heating and cooling seasons shorten life); 2) number of occupants and pets; 3) smoking, candle use, or home projects; 4) nearby construction or harvest dust; 5) wildfire smoke events. We check the pressure drop during each bi-annual maintenance visit and recommend replacement when it hits the manufacturer’s limit, not just a set date on the calendar.
Do high-MERV media filters really help with allergies, asthma, and airborne viruses?
Yes. A properly sealed MERV 13 filter removes 90%+ of particles down to 1 micron—enough to capture pollen, pet dander, and mold spores that trigger allergies and asthma. MERV 14-16 filters catch even finer particulate (0.3–1 micron), including many bacteria and the droplets that carry influenza and COVID-19. While no filter guarantees complete protection, combining high-MERV filtration with adequate ventilation and humidity control dramatically improves indoor air quality for sensitive occupants.
Will switching to a high-MERV filter save money or raise my energy bills?
A clean high-MERV media filter typically adds less than $1 per month to operating costs. Because it traps dirt before it coats the blower wheel and indoor coil, the system actually runs more efficiently over time. Cleaner coils transfer heat better, the blower motor doesn’t fight accumulated dust, and you avoid expensive service calls for restricted airflow. Many homeowners see lower total utility and maintenance costs over the filter’s lifespan compared with using multiple cheap 1″ filters.
