When it comes to air purification, there are a variety of technologies available, each with its own advantages and disadvantages. HEPA air purifiers typically have a first-pass efficiency rate of 87 to 99 percent, making them more effective than electrostatic air purifiers, which have a first-pass efficiency rating of 60 to 80 percent. A true HEPA filter is 99.97% efficient at removing dust particles from 0.3 microns to 10 microns, while a LakeAir electrostatic cell is 97% efficient in removing dust particles from 0.1 micron to 10 micron.
HEPA
is clearly the best type of filtration when it comes to efficiency numbers alone, but it's important to consider all the variables when deciding on the best air purification technology for your individual circumstance. An electrostatic filter is more durable than a traditional pleated filter and can last longer, but it's not necessarily the best air conditioning filter on the market.The term “electrostatic air filters” can refer to an air purifying unit that uses electricity to charge particulate matter, or a disposable filter panel that is normally placed in a heating, ventilation, and air conditioning (HVAC) system. An electrostatic air filter unit generates electric fields to trap particulates (referred to as an electrostatic precipitator in industrial terms). To decide if an electrostatic filter is right for you, it's important to weigh the advantages and disadvantages. You can go to just about any hardware store or major retailer in the United States and buy a pleated air filter, but electrostatic filters aren't as common and many homeowners don't know they exist.
These filters capture smaller particles than traditional filters, but the typical home air conditioner or oven isn't powerful enough to draw air through them. Depending on the quality of the electrostatic filter, this process can be repeated several times before the air is cleaned and returned to the system. The same rules also apply to electrostatic air filters, although the MERV classification isn't that worrisome. Electrostatic filters use electromagnetism to remove particles from the air and are more effective than conventional air filters at capturing small particles, such as dust and pollen. The cost of a washable electrostatic filter depends largely on the size, since most filters are multi-layered and also have “limited lifetime warranties”.
HEPA filters are very effective in improving indoor air quality and can even reduce harmful pathogens. As with pleated air filters, quality is important when it comes to electrostatic filters, and so is maintenance. An important note is that electrostatic cells must be cleaned regularly or their efficiency will decrease. In conclusion, when it comes to choosing between an electrostatic filter and a traditional pleated filter for your home, it all comes down to weighing the pros and cons of each option. HEPA is clearly the best type of filtration when it comes to efficiency numbers alone, but other factors should be taken into consideration before making a decision.
