High Efficiency Particulate Air filter is an air filter that meets certain efficiency standards, such as the efficiency standard set by the US Department of Energy (DOE.Many also use the HEPA filter as part of the filter system.This is beneficial for patients with asthma and allergies, as the HEPA filter captures particles (such as pollen and dust particles) that trigger allergy and asthma symptoms ).In order for the HEPA filter in the vacuum cleaner to be effective, a vacuum cleaner must be designed in order to discharge all the air sucked into the machine through the filter, and all the air has not been missed.This is often referred to as a \"sealed HEPA\" or sometimes a more vague \"real HEPA \".\"The vacuum cleaner that simply attaches the HEPA label has a HEPA filter, but not all air has to go through it.Finally, as \"HEPA-Like \\ \"usually a filter with a similar structure to HEPA is used, but there is no filter efficiency.Due to the high density of the HEPA filter, a stronger motor is needed to provide adequate cleaning capability.Due to \"washable\", the newer model claims to be better than the first one.Generally, washing-resistant filters are very expensive.Some manufacturers claim to filter standards such as \"HEPA 4\" but do not explain the meaning behind it.It refers to their lowest efficiency report value (MERV) rating.These ratings are used to rate the ability of the air filter to remove dust from the air when passing through the filter.MERV is the standard used to measure the overall efficiency of the filter.The MERV scale ranges from 1 to 20 and measures the ability of the filter to remove particles from 10 to 0.Size is 3 microns.A filter with a higher rating can remove not only more particles in the air, but also smaller particles.
