What is a HEPA Vacuum Cleaner
Lets be clear on the difference between a normal vacuum cleaner and a hepa vacuum cleaner. Both clean your home and functionality is almost same.
But here is the real difference:
HEPA vacuum cleaners are specialized for their ability to absorb dust and allergen particles. Yes, they are great tools to clean your home/office if you are suffering from allergy or asthma caused by dust/pet hair.
The term ‘HEPA’ stands for high efficiency particulate air. If a vacuum filter should be categorized as HEPA filter, it must absorb all dust particles 0.3 microns in size or larger at an efficiency level of minimum 99.97%
This means that, the HEPA filtration system can absorb the small dust particles that other normal vacuum cleaners would not catch. This prevents the re circulation of allergy causing dust and bacteria.
If you are a dust allergy sufferer and planning to buy a allergy free vacuum cleaner, make sure to check that the device has a HEPA filter in it.
What is HEPA filter in vacuum cleaner?
Like I said above, it is the specific filter included in anti allergy vacuum cleaners to combat agains dust and pet hair. HEPA filter is specifically useful for you if you are suffering from allergy or asthma related health issues.
In general, all the vacuum cleaners with HEPA filters would add the specification in their prodct description. I suggest you to read through the product description in detail, so that you can be sure that you are buying a real HEPA enabled vacuum cleaner.
HEPA vacuum bag
HEPA vacuum cleaner bag and all the components should be tightly sealed in order to ensure that there is no leakage of dust air. Also, you have to check the hepa bag at regular intervals and make empty the dust bag. This way you can maintain the hepa vacuum cleaner in a more efficient way.
Keep in mind, if you are an allergy victim do not clean the HEPA vacuum bag yourself. It can cause you trouble. So get help from someone who does not suffer from allergy to clean the dust bag.
EPA approved hepa vacuum cleaners
EPA standard: According to the EPA, a HEPA vacuum is one “designed with HEPA as the last filtration stage,” where “all the air drawn into the machine is expelled through the filter with none of the air leaking past it.”
So if a vacuum cleaner designed for HEPA specification but is not well sealed or which fail to absorb dust particles with 0.3 micron in size will be treated not as a HEPA vacuum.
