Arm & Hammer Filter

A MERV 11 rating indicates that this filter is more efficient at capturing small particles than standard MERV 8 filters. It is capable of trapping up to 85% of airborne particles, including dust mites, mold spores, and pet dander, making it a strong choice for allergy sufferers.

The activated carbon layer is designed to absorb and neutralize common household odors, such as those from cooking or smoke. The addition of baking soda provides an extra layer of freshness to help keep your indoor air smelling clean.

While this filter provides superior filtration, it is specifically engineered to maintain optimal airflow. However, you should always ensure your HVAC system is compatible with a 1-inch pleated filter to prevent any strain on your blower motor.

No, this is a disposable filter. Because it uses electrostatic media and an activated carbon layer to trap particles and odors, it cannot be cleaned or washed and should be replaced according to your system's maintenance schedule.

While replacement frequency depends on your specific environment, pets, and usage, most 1-inch filters should be replaced every 90 days. If you have multiple pets or high levels of dust, you may want to check the filter sooner to ensure it isn't clogged.
