CF21 CRYSTALA Filters

Review CRYSTALA Cf21/zo21 Filters

Crystala CF21 CF21/ZO21 filters are advanced replacement air filters designed to ensure cleaner and healthier air in your home. These filters are compatible with various HVAC systems, including those using CF21, CF21/F, or ZO21 filter sizes.

The CF21 CF21/ZO21 filters are pleated, meaning they have multiple layers of filter media, increasing their surface area to trap more airborne particles. The filter media is made from a synthetic material that is electrostatically charged, which attracts and captures particles as air passes through it.

These filters have a MERV (Minimum Efficiency Reporting Value) rating of 11, which makes them effective at trapping small particles such as pollen, dust mites, bacteria, and even some viruses. They also have a high airflow rating, ensuring efficient air filtration without putting excessive strain on your HVAC system.

The Crystala CF21 CF21/ZO21 filters are washable and reusable, making them a cost-effective solution for those looking to reduce their environmental footprint. To clean the filter, simply remove it from the filter housing, rinse it under warm water, and let it air dry before reinstalling it.

These filters come in a standard size of 16 x 25 x 1 inches and are available in packs of 3, 6, or 12, making it convenient for homeowners to stock up on filters for their HVAC systems. Additionally, the filters come with a frame, which makes installation easy and hassle-free.

Overall, the Crystala CF21 CF21/ZO21 filters are a high-performing and cost-effective solution for those looking to improve the air quality in their homes. They are easy to install, maintain, and provide efficient filtration, ensuring that you and your family can breathe easy and live comfortably.
