This is frequently generally known as "Sealed HEPA" or sometimes the more vague "Correct HEPA". Vacuum cleaners only labeled "HEPA" can have a HEPA filter, but not all air necessarily passes as a result of it. Lastly, vacuum cleaner filters promoted as "HEPA-like" will typically utilize a filter of a similar construction to HEPA, but with no filtering efficiency. Due to the more density of a true HEPA filter, HEPA vacuum cleaners involve extra strong motors to offer sufficient cleaning power.[citation essential]
By picking approved click here HEPA filters, you present the ideal air top quality yourself and those around you. Non-authorized filters may well not supply the exact same volume of performance, resulting in lessened usefulness and possible wellbeing threats.
