Product Information

Additionally, if you’ve made the mistake of washing your Henry vacuum’s filter with water, then you’ll probably need to replace it. Once dust and dirt become mud inside the filter, it’s virtually impossible to remove. On the other hand, if you just have hard floors, then the streamlined hard floor-specific head is the one to grab. In fact, this head is one of the very best hard floor heads I’ve ever used. It’s really flat, like a sleek sports car, but it performs superbly well and feels fabulously smooth to push around. A high-five to Numatic’s R&D department for this radical piece of engineering.

No, Henry filters should not be put in the washing machine. Water can clog the filter and they aren’t designed to withstand a wash cycle. Henry filters are not washable. You shouldn’t use a wet cloth, run them under a tap, or put them in the washing machine, as this will cause the dirt to turn into mud. Once that happens, the filter will probably become too clogged and need to be replaced. This is a premium compatible part that has been expertly designed for use in medical surroundings. Use around the home stops dust from re-entering the air. A god send for those with allergies. Keep in mind that the filter is never going to appear as white and clean as when you first bought it. The goal is to remove as much dust as possible – not to restore the filter to its original appearance. A single power switch turns the vacuum cleaner on and off. Note that there are no selectable power modes, bar the aforementioned vent. PerformanceIf your vacuum cleaner has a HEPA filter then it will keep hold of dust that is less than 1 micron in size. A bag that’s more than 75% full may reduce suction. This is because the air must be forced through all the collected debris. The label under the handle on Henry, Hetty or Harry (or on the rear of your machine for James, Charles & George) will contain the model number.

With normal filters air passes through a sheet with holes and larger dust particles get trapped in the holes that are big enough to let air through but too small to let large dust particles and things like hair pass through. All filters are not the same and the cheaper ones will not filter out a lot of the dust a filter can only be called a HEPA filter if it keeps hold of 99.97% of all dust particles. Unfortunately it’s not a regulated market so be wary of any marketing material that states anything such as “HEPA LIKE” or anything like that. If you’ve cleaned a lot of dirt and dust from the filter, you might be surprised by how much more suction power Henry can now generate! When Should You Buy a New Henry Filter?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)! How much dust stays inside the hoover depends on the kind of filtration system that it has and the better the filter the more dust that stays inside the vacuum cleaner and the cleaner your home is. If you look at a HEPA filter it looks like some kind of material that has been folded up but is actually glass fibres that catch very fine particles. HEPA Filters have become pretty common in everyday life.They’re used in fans, dehumidifiers, air conditioning (both in buildings and cars) and evenvacuum cleaners. Most people are aware they're the most thorough filters available for domestic appliances, but what isn’t as widely known is why!
