THE AIR WELLNESS
HELP DESK.
Product, fit, timing, control, and the limits every buyer deserves to understand.
01What is MERV 11?+
MERV is a standardized rating for particle filtration. MERV 11 indicates performance across defined particle-size ranges. It is not a medical or universal indoor-air-quality score.
02What does the carbon backing do?+
Activated carbon can help adsorb certain gases and odors. Effectiveness varies with the pollutant, airflow, contact time, and amount of carbon.
03How often should I change the filter?+
There is no universal schedule for every home. Follow equipment and filter guidance, consider system runtime and household conditions, inspect the filter, and adjust the cadence.
04What if I do not know my size?+
Use the guided size finder. The nominal dimensions are often printed on the edge of the current filter. Do not guess when system fit is uncertain.
05Can I order more than one size?+
Yes. Add each return’s size and quantity, then review every line item together before checkout.
06Can I pause, skip, reschedule, or cancel?+
Yes. Review the next shipment before it leaves, then pause, skip, reschedule, or cancel as the home’s needs change.
07How much does TRU cost?+
TRU starts at $27 per filter with free shipping. A $27 monthly example is about 90¢ a day. Other quantities and cadences change the daily math.
08Does a TRU filter solve every indoor-air problem?+
No. Filtration supplements source control and appropriate ventilation. No residential HVAC filter removes every pollutant, and system compatibility matters.
Still need the size?
Find the dimensions on the current filter, or use the guided size finder before you order.
