Buy Replacement Air Filters

Air filters help improve indoor air quality by removing dust, pollen, pet dander and other airborne allergens. They also reduce odours and help prevent the spread of bacteria and viruses, creating a cleaner, healthier environment for you and your family.

We recommend replacing the air filters in your home every 6 to 12 months. However, the frequency may vary depending on the type and grade of filter you use, and whether you have pets, allergies or live in a high‑pollution area.

Popular home air‑filter options include MVHR filters for heat recovery systems, HEPA filters, and activated carbon filters. Each type serves a different purpose, offering its own benefits depending on your system and air‑quality needs.

Air filters can help reduce the spread of cold, flu, and COVID‑19 viruses by continually cycling the air in your home. While they can’t prevent illness on their own, regularly extracting stale air and filtering incoming fresh air helps lower the amount of airborne droplets in your living space, supporting better overall indoor air quality.

You can buy home air filters directly from FiltersDirect.uk, where you’ll find a wide range of sizes and types for most systems. Selecting the right filter for your system helps maintain good airflow and filtration performance.

For MVHR units, M5 grade filters are one of the best options for allergy sufferers, as they capture a high percentage of fine particles such as pollen, dust, mould spores, and other common allergens. M5 filters are designed to remove particles in the 1–10 micron range, making them ideal for improving indoor air quality and reducing allergy symptoms while still allowing your MVHR system to maintain good airflow.
