EverFilter is a reusable aluminum-framed HVAC filter system designed to reduce disposable filter waste while maintaining airflow. Depending on the product variant, EverFilter may use:

• Refillable filter media pads
• A permanent, washable electrostatic multi-layer filter

Each product page clearly states which version applies.

The frame is reusable indefinitely. Media handling depends on the specific EverFilter product:

• Some models use replaceable media pads
• Some models use a permanent, washable electrostatic filter

EverFilter products do not combine these systems. The product page will clearly indicate which design you are purchasing.

EverFilter products are designed with airflow in mind. Like all filters, restriction increases as the filter loads with debris. Proper sizing, installation, and maintenance are critical. We recommend following HVAC manufacturer guidelines and replacing or cleaning filters on schedule.

EverFilter is designed for standard residential and light commercial HVAC filter housings, typically 1" or 2" nominal depth. It is not designed for:

• Custom housings outside standard depths
• HEPA cabinets
• Powered electronic air cleaners

If you are unsure, contact support before ordering.

Service intervals depend on the product type and environment:

• Replaceable media systems: typically every 30 to 90 days
• Washable electrostatic systems: clean every 30 to 60 days

High dust environments may require more frequent service.

Yes. We supply commercial and industrial HVAC filters including panel filters, 12" box filters, pocket bag filters, and specialty configurations depending on availability.

Commercial filters may be subject to different return policies, especially for bulk orders, special sizes, or made-to-order products. Refer to the product page or contact support before ordering. Return shipping must be paid and all products must be unopened and unused. 14 day return only.

Some commercial filters may fit residential systems, but they are not always appropriate due to airflow, pressure drop, or system design. We recommend using products designed specifically for residential HVAC unless advised otherwise by a professional.

The Air Test Kit is a consumer indoor air screening tool designed to help identify the possible presence of common indoor contaminants. It is intended for awareness, not diagnosis.

Results are processed through qualified laboratories; however, the kit does not replace professional inspections or medical testing. It provides general insights into indoor air conditions.

Once an Air Test Kit has been opened or used, it is not eligible for return due to contamination control and handling requirements.

No. The Smart AirSense Monitor does not filter or clean air. It measures and displays indoor air quality data in real time.

No. It operates independently and does not connect to, control, or modify HVAC equipment.

No. It is designed for trend monitoring and awareness, not clinical or regulatory compliance.

Orders may be canceled only before processing or shipment. Once an order enters fulfillment or ships, it cannot be canceled.

Yes. Subscriptions can be canceled or modified through your customer portal at any time before the next billing date. Canceling a subscription stops future shipments only.
