First4Spares Premium HEPA Filter for Numatic Henry Hetty, George, Basil Charles etc Tub Vacuum Cleaners - The New Generation of Henry Filters

Product Information

The Henry range is beloved for good reason: the vacuum cleaners are powerful, simple to use and deliver a huge amount of power. I measured the raw power of the Henry Allergy HVA160 at a massive 402AW, dropping to only 281AW with the vent open. That’s about the same power as the Stihl SE 33 wet and dry cleaner, and a lot more powerful than the Shark CZ500UKT.

The only slight issue is that the metal poles do have a tendency to become stiffer over time and therefore more difficult to pull apart. I recommend you separate them at the end of every clean as a preventative measure. This size of dust particles is measured in microns. 1 micron is one-millionth of a metre, way too small to be visible to the human eye.

Cleaning the filter on your vacuum cleaner at least once a month is recommended to ensure that there is no loss of performance and it is still collecting all of the tiny particles that it is made to do.

The Henry Allergy HVA160 adds boosted HEPA filtration to the mix, preventing any harmful particles from escaping into the wild. If you have a home with allergy sufferers, then it’s an excellent choice. Design and Features If you have access to another vacuum cleaner, use it to vacuum both sides of the filter. Make sure you clean all areas of the filter including the sides. This is an effective way to remove more dirt than just tapping off loose debris. A bag that’s more than 75% full may reduce suction. This is because the air must be forced through all the collected debris.

Full specification

HEPA Filters must satisfy a certain levelof efficiency. The HEPA (H13) filter in Henry Allergy is certified to clean, trap and eliminate particlesdown to 0.3 microns at 99.97% efficiency. That’s particles up to300 times smaller than a single grain of sand (90μm)! If you haven’t cleaned the filter for a while, you’ll immediately notice how dirty it’s become. The more dirt collected on the filter, the less suction your Henry can generate. To access the filter, you need to take off the lid of your Henry using the same method as when replacing the bag. If your vacuum cleaner has a HEPA filter then it will keep hold of dust that is less than 1 micron in size.
