Electrostatic Air Purifiers and Air Cleaners
LakeAir is famous for its Electrostatic Air Purifiers. We have been making this filtration type air purifier for over 50 years. The electrostatic filter is falsely maligned by many in the Air Purifier industry. It should not be viewed as bad or good. It is a filtration type with both positive and negative points. To read more about this battle of filter technology you can read our popular article Electrostatic vs HEPA.
What Makes Electrostatic Air Cleaners Work?
Electrostatic precipitators consist of wires and collection plates. A high voltage from a field between the wires and collecting plates—gives the air an electric charge and creates an ionizing section through which the polluted air passes.
The polluted particles are also charged, but theirs is opposite to that of the collecting plates. The plates attract the particulates, which attach themselves to the surface, leaving clean air to go through.
The airborne particulates build up on the plate and reduce the electrostatic air cleaner’s effectiveness. Therefore, the plates must be removed and washed to restore optimum functioning. The cleaning of the plate depends on factors that affect the air quality in your home.
For example, if you live with a dog and two cats, the dander, shedding, and odor will build up more quickly than not having pets. You would then have to clean the electrostatic precipitator frequently.
However, if you live on your own and seldom entertain guests, particulate build-up would be much slower—giving you more time between washes.
How Efficient are Electrostatic Air Cleaners?
Electrostatic air filters are very good at what they’re designed to do, which is to filter out common allergens and harmful particulates such as dust, dust mites, pet dander, smoke, and mold spores.
According to the Environmental Protection Agency (EPA), electrostatic precipitators are 98% efficient at removing fine airborne dust particles from surfaces. However, this is provided that the electrostatic plates are clean.
There is an additional caveat, particle size affects efficiency. Larger particles, mid-range particles, and very small particles charge differently, and only certain sizes stick to the plate. This means that some harmful airborne particulates pass straight through the cleaners and re-enter circulation.
What Counts Against Electrostatic Air Cleaners?
Ozone production is the biggest problem with electrostatic air cleaners. These emissions are a byproduct of the electrostatic air purifier’s process.
Ozone is a harmful chemical that can worsen respiratory problems and create lung damage. While electrostatic air filters don’t produce nearly the same levels of ozone as generators, it’s worth noting the potential risk.
LakeAir Electrostatic Air Cleaners Have Quality Where It Counts
LakeAir has been producing electrostatic air filter units for over 50 years. Our processes have been refined over the years, and we now offer some of the most efficient and effective air filtration systems available.
Many of our units have activated carbon fiber filters that improve their ability to remove fine air particles from indoor spaces. They are quiet, which makes them perfect for bedrooms and other areas that need virtual silence. They can be ceiling-mounted or wall-mounted, and in cases where there is no drop ceiling, they can be hung.
An electrostatic air cleaner is perfect for situations where all you want to do is improve indoor air quality. If your needs are greater and you need a system that cleans the air to safe levels and removes all health risks, then you should consider one of our HEPA air purifiers.

Electrostatic Air Purifier Issues
Like many other things, when your electrostatic unit is working well it’s great. When they are not functioning properly it can be a down right pain. There are usually 3 things that will keep you electrostatic air cleaner from cleaning the air.
(1) Dirty Filter Cells
When a LakeAir electrostatic air cleaning device is freshly cleaned it is about 97% efficient. As the electronic filter gets dirty, it looses efficiency. Depending on the environment this efficacy can drop by as mush as 4% per week. It is very important to clean your filter cell often. In most cases we suggest at least every 3 months.
(1) Damaged Filter Cells
During shipping or handling an electrostatic filter cell can become damaged. Many times the damage will cause the electronic filter cell to short out. When the electricity cannot flow through the filter it no longer has the ability to remove particles from the air. Inspecting you filter cell for damaged plates or missing or broken wires can often point you to the reason for your lack of air purification success.
(1) Bad Power Supply
A well built power supply will last for many years. But like all things, a power supply will fail eventually. The power supply provides the needed electrical current that causes the electro magnetic attraction that is the basis for this filter technology.
The power supply could still function but become to weak to allow the electrostatic functionality. Due to the high voltage its not easy to test your power supply. The spark created at the filter should be strong. If your unit sounds like a bug zapper than you power supply is probably good. This Video covers many of the issues encountered when trying to troubleshoot problems with an electrostatic air purifier.

The LA14000-s is built for commercial and light industrial use. This unit is economical, reducing heating and air conditioning costs as a result of not having to exhaust contaminated air and recondition replacement air. Units can be mounted in a number of ways to suit your preferences and specific application needs.
Commonly referred to as “whole house systems”, our in-duct air purifiers are ideal for residential forced air systems. The LAD will remove mold, pollen, pet dander, dust and many other allergens. If you keep the carbon after filter changed regularly you will remove formaldehyde and radon from your entire home.
The LAD1814 is commonly referred to as “whole house filtration system”. The LAD will remove mold, pollen, pet dander, dust and many other allergens. If you keep the carbon after filter changed regularly you will remove formaldehyde and radon from your entire home.
