The main purpose of a vacuum cleaner is to clean a house by removing dust. How effectively it can remove dust will depend on the model and the brand of the vacuum. However, regular cleaners can only remove dust particles that are 30 – 50 microns. Bacterial particles and allergens such as house dust mites are less than 1 micron in size, this means that although they can clean you house, they do not totally remove harmful allergens. That is why HEPA filter vacuum cleaners were created.
Vacuum cleaners that trap particles that are .3 microns or lower in size 99.97% of the time are considered HEPA Rated. By the way, HEPA stands for High Efficiency Particulate Air. Remember that not all vacuum cleaners are HEPA rated. A test is conducted on them and if they pass, they get a serial number. This is the proof that they are indeed HEPA rated.
Aside from this unique feature, HEPA filter vacuum cleaners are just like regular vacuum cleaners. They can be of different types too such as uprights, canisters and even handhelds. The can vary in size, shape and weight. However, the price of these vacuum cleaners is much higher than the regular ones.
A lot of companies offer these types of vacuum cleaners. The question to ask is why anyone should buy these vacuums? The main reason to buy one is the advantage of having an allergen free home. If you are an allergy sufferer or if you have asthma, you know that living in a clean house and breathing clean air is important. HEPA filter vacuum cleaners can provide that kind of environment. So whether you are that kind of a person or you just want a clean and healthy home to live in, these vacuum cleaners are well worth the price you pay.
