An air purifier can help improve indoor air quality by reducing allergens and unwanted household odours. To keep your purifier performing at its best, it’s important to maintain the HEPA filter and replace it according to the manufacturer’s recommendations.
How Often Should a HEPA Filter Be Replaced?
The lifespan of a HEPA filter depends on several factors, including how often the purifier is used, the air quality in your home, and whether pets or allergy sufferers are present.
For typical household use, replacing the filter is generally recommended:
•every 6–12 months for everyday use;
•every 3–6 months in environments with higher levels of dust, pollen, or pet hair;
•according to the manufacturer’s guidelines or when the purifier indicates that the filter should be replaced.
HEPA Filters: Not All Are the Same
The term HEPA refers to a family of high-efficiency air filters, but there are different filtration classes available.
The most common include:
•HEPA H13, capable of capturing at least 99.95% of fine airborne particles according to European standards.
•HEPA H14, offering even higher efficiency by capturing at least 99.995% of airborne particles.
The right filter depends on your air purifier model and the environment where it is used.

Allergens and Household Odours
During everyday use, a HEPA filter captures a wide range of airborne particles, including household dust, pollen, pet hair and dander, mould spores and fine particulate matter.
Many air purifiers also include an activated carbon filter, which helps reduce common household odours such as cooking smells, pet odours, and stale indoor air.
Choose the Right Replacement Filter
Using a replacement filter specifically designed for your air purifier helps maintain its efficiency and ensures reliable performance over time. Genuine or compatible replacement filters allow the filtration system to continue working as intended, helping you enjoy cleaner indoor air every day.
Taking care of your air purifier means taking care of the air you breathe.
