Filtrete Smart Replenishable AC Furnace Air Filter

Unlike a standard timer, the built-in Bluetooth sensor monitors actual HVAC airflow and usage. This means you receive a notification based on how much your system has actually worked, rather than an arbitrary date, ensuring you replace the filter only when necessary.

An MPR 1900 rating indicates a high level of filtration, equivalent to a MERV 13 rating. It is designed to capture microscopic particles like bacteria, viruses, smoke, and fine allergens, making it a strong choice for households concerned with indoor air quality or respiratory sensitivities.

While this filter is highly efficient at trapping small particles, it is designed for standard and high-efficiency furnaces. If you have an older system with a weak blower motor, you may want to ensure your HVAC unit is rated to handle a MERV 13-level filter to maintain optimal airflow.

The filter's sensor tracks data independently as your HVAC system runs. You only need to open the Filtrete Smart App periodically to sync the data via Bluetooth and check your current filter life status.

Yes, the actual dimensions are 19.69 x 19.69 x 0.78 inches, which is the industry standard for a '20x25x1' filter. It should fit most standard furnace or air conditioner return vents designed for this size.

Yes, the filter functions perfectly as a high-quality air filter even if you choose not to pair it with the app. You will simply lose the automated tracking and replacement notifications.
