For regular homes, an H13 grade HEPA filter works just fine. If you’re trying to get rid of formaldehyde after doing some renovations, it’s best to go for a composite filter that combines HEPA with activated carbon or catalytic decomposition. HEPA filters catch tiny particles, while the activated carbon or catalytic layer absorbs and breaks down harmful gases like formaldehyde and benzene. Make sure to choose products that use catalytic decomposition technology to prevent any secondary pollution once the activated carbon gets saturated.

The HEPA filter grade in vacuum cleaners is also important. An H13 grade true HEPA filter stops fine dust from escaping through the exhaust while vacuuming, making it ideal for small spaces. This is especially crucial for families where kids often play on the floor. When shopping, steer clear of products that just say “HEPA” without mentioning the grade, as some cheaper options are only “HEPA-like” and might not filter effectively, with efficiency possibly below 80%.


Note: Vacuum cleaners are insufficient to remove dust mite bites; other environmental protection measures are necessary.

Nowadays, more new cars come with HEPA filters as standard, and some even have “biochemical-grade” HEPA filters that can filter out over 99% of 0.3-micron particles, which is way better than regular air conditioning filters available. For older vehicles, you can swap out the filter for a HEPA + activated carbon composite filter to significantly enhance the air quality inside the car. It’s generally recommended to replace it every year or after driving 20,000 kilometers.
