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!
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. 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. Henry Hoover filters cannot be washed with water, as the dust and dirt will turn into mud. Start by tapping off loose debris into a bin. Then use a second vacuum cleaner to remove dust from both the inside and outside of the 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)! As Henry filters aren’t washable, they occasionally need to be replaced. Henry filters are widely available – just make sure you buy the right filter for your model.

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 you need to do is remove it from the vacuum cleaner and run it under some cold water until you have visibly removed the dust that you can see. Henry Allergy has just one power setting but you can adjust the suction to some degree by swivelling a valve on the head of the suction tube. But here’s the rub… While the valve helps dial down the suction, there’s still way too much of it when used on a carpet, even with the bristles raised. It’s not terrible but it just takes extra effort to push and pull it across the carpet. Put another way, it doesn’t glide across carpet like a Dyson or a Shark. 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.
When it came to the hard floor test I had a choice of two main floor brushes. The ‘universal’ brush head comprises a simple surround of stiff bristles that can be retracted for carpet use – this is the head you will use the most if your home has a mixture of hard floor and carpet since it’s easy to simply stamp on the large retractor switch as you change surfaces. If your vacuum cleaner has a HEPA filter then it will keep hold of dust that is less than 1 micron in size. 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. Henry Hoover filters can’t be washed with water. Instead, you should remove as much dust as possible by tapping off the loose debris into a bin, then vacuuming the filter with another vac. If you don’t have another vacuum, then a soft (dry) brush can be used to remove dirt.A HEPA filter makes sure that tiny particles of dust stay inside your hoover when you are cleaning.
No. HEPA filters quite expensive to manufacture so one of the ways to keep the price down is to put a standard filter in which is quite common on low-cost hoovers.

To access the filter, you need to take off the lid of your Henry using the same method as when replacing the bag.Tip: Don’t have a spare vacuum? You can use a soft brush to remove loose dirt and other debris, although this won’t be as effective. Step 4: Replace the Bag But what does HEPA actually stand for? Well…. It depends who you ask but they all mean the same thing; less allergens, irritants and dust in your home. A single power switch turns the vacuum cleaner on and off. Note that there are no selectable power modes, bar the aforementioned vent. Performance 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.
