Know before you buy
Standard filters often allow air to leak around the edges, bypassing the filtration media entirely. The Biosponge Plus uses a patented seal that forces 100% of the airflow directly through the filter media, ensuring that all dust and allergens are captured.
The Ageis Microbe Shield is a treatment applied to the filter media that actively inhibits the growth of germs, bacteria, and mold on the filter surface. This prevents the filter from becoming a breeding ground for microbes, keeping your indoor air cleaner.
Yes, the dual-density, MERV 13-rated synthetic media is specifically designed to capture fine dust particles and common household allergens. Its high-efficiency design makes it an excellent choice for improving air quality in homes with pets or residents sensitive to airborne irritants.
This refill is designed for use with specific Airteva and Healthsmart filter frames. Because it is a custom-sized product, ensure your existing frame is compatible with the Biosponge Plus system before ordering.
The replacement process is designed to be quick and simple. You simply peel out the old, used pad from your existing heavy-duty aluminum frame and insert the new Biosponge Plus refill pad.
The 60-day interval is the recommended standard for optimal performance and airflow. However, if you live in an area with high dust levels or have multiple pets, you may find that replacing the pad slightly sooner helps maintain your HVAC system's efficiency.
