How do Ionic air purifiers work?

Ionic air purifiers have been known to be helpful against a variety of infections and allergies. They have helped thousands of people maintain healthy homes and dust free spaces for years now.

Ionic purifiers are essentially filterless units. These devices can work in two ways:

1. Electrostatic Precipitators

Electrostatic precipitators have positive and negatively charged plates inside of them.

As air flows inside these devices, impurities in the air collect on these plates. This is why, these plates need cleaning at regular intervals of time so that they maintain their cleaning efficiency.

2. Air Ionizers

Air Ionizers work differently from electrostatic precipitators, and are also called Negative Ion Generators.

This is because these devices emit an increased concentration of negative ions into the surrounding air. The emitted negative ions then get stuck to airborne particles like dust, pollen and mold spores.

These airborne particles take over some of the negative charge and become negatively charged themselves.  Once this happens, these particles are either attracted back inside the air purifier or allowed to settle on surrounding surfaces like the floor, walls and furniture in the house.

Additional technologies used in air purifiers

Several technologies are used today separately, or in conjunction to improve the quality of air purification. These Top 15 Best Ionic Air purifiers in 2019technologies when used in conjunction, serve as additional layers in the process of air purification.

Here are some common technologies/filters used today in addition to Ionic purification:

1. HEPA filter

The HEPA filter is considered to be the Gold Standard in the list of air purification technologies. True HEPA filters are incredibly useful in filtering bacteria, toxins, dust, pollen, and mold from the surrounding air.

If you’re looking for an air purifier that uses HEPA filters, beware of cheaper filters marketed under the name of “HEPA-like” filters. These do not offer the same air purification efficiency as pure-HEPA filters.

Also, HEPA filters purely work on the basis of mechanical air filtration. These do not emit any dangerous gases like Ozone into the atmosphere, and thus are considered to be the safest and best choice in air purification.

2. Activated Carbon filter

Activated Carbon Filters are often used along with other purification technologies or filters, and effectively help filter odors, chemical vapors and smoke from air.

These filters use oxygen to trap vapors, odors and other irritants in air to leave behind fresh, pure air. Activated carbon filters need replacement every few years to ensure optimum performance.

3. Pre-filters

Pre-Filters are generally placed as the first level of purification in an air purifier. These help filter out larger impurities like pet hair and dander, and increase the efficiency across purification stages that follow.

These filters are usually made out of foam or polyester.

4. Ozone GeneratorsTop 15 Best Ionic Air purifiers in 2019

Though ionic air purifiers are said to emit a very minute concentration of Ozone, there are devices that emit a large concentration of Ozone to purify air.

Though a good quantity of Ozone helps rid the air of any impurities that may be present in it, the gas can be extremely harmful and toxic for humans.

Ozone is a major lung irritant and Ozone generators can reduce the oxygen supply in a room. This is why, ozone generators are never recommended to be used in homes for purification purposes. They are banned in many places, and are only used in commercial spaces.

5. UV technology

UV filters help sterilize the air of any harmful microbes that may be present. These are greatly beneficial and help reduce risk of airborne diseases and infections.

These filters use a combination of a UV light emitting lamp and traditional filters to operate.

6. Cold catalyst filter

Cold Catalyst filters are used to eliminate VOC’s like formaldehyde from the surrounding air. While these filters may not find large uses in domestic spaces, they’re extremely beneficial in lab environments.

7. Germicidal and Anti-bacterial filters

Anti-bacterial and germicidal filters do a good job of filtering out harmful microbes and micro-organisms, bacteria and viruses from the surrounding air. These are especially helpful in spaces where cleanliness is top priority.

8. Charged media filter

Charged media filters have a working that’s very similar to Electrostatic precipitators discussed above. But unlike the Electrostatic precipitators, these do not come with charged plates.

They use filters instead.

Things to consider while choosing an air purifierTop 15 Best Ionic Air purifiers in 2019

Now that you know the different techniques and technologies used in air purification, here are some basic factors to take into consideration while purchasing an air purifier.

1. Room size

Air purifiers are usually designed to be used in single rooms. If your space is bigger, you will need a larger air purifier. While choosing an air purifier, it is recommended that you opt for a unit that is designed for areas that are 20 to 40% larger than your room area. This will help ensure optimal performance.

2. Amount of Ozone generated

While buying an air purifier, always check for the level of Ozone the purifier generates. While ionic air purifiers emit ozone in tiny amounts, the standard for health safety is an Ozone emission level that’s less than 0.05 ppm.

While we suggest that you avoid ozone generators altogether, it is advisable to always check this metric in other air purifiers.

3. Noise levels

When you plan to keep an air purifier on for most of the day, it is important to take its operational noise into consideration. Some air purifiers (mechanical ones, especially) give out huge amounts of noise during operation.

Noise levels are a major factor to consider for an equipment that’s always running in the house – for the sake of your sanity.

4. Operational costs

For most air purifiers, initial cost of purchase is just a part of the investment. Air purifiers often need regular maintenance including filter replacements, servicing, and will incur regular electricity costs.

While purchasing purification systems with filters, take time to consider the types of filters used, and their filter replacement requirements and costs.Top 15 Best Ionic Air purifiers in 2019

To help reduce hefty electricity bills, look for energy efficient models and the ones that are Energy star certified.

5. ACH and CADR

ACH stands for Air Changes per Hour. It is a measure of how often the air purifier can clean the claimed coverage area in one hour. For example, if an air purifier has an ACH value of 4, it is capable of purifying air every 15 minutes.

While choosing an air purifier, it is always advisable to opt for an air purifier that has an ACH value of at least 4.

ACH is an extremely important measurement of an air purifier’s efficiency, because air in a space can be constantly contaminated by external sources.

Another measure of an air purifier’s capability is CADR (Clean Air Delivery Rate). Though not as important as ACH, it is also a useful performance metric.

Regular maintenance and care will ensure that your air purifier stays in top shape for the years to come. Here are some tips to help you take good care of it.

  1. Eliminate dust in your space as much as possible. Having an air purifier does not mean you let your house be a rotting, dusty mess expecting the air purifier to do all the work for you. Eliminating the dust as much as possible on your own will help your air purifier take up the more minute aspects of purification and catch allergies you did not see coming.
  2. Clean the grills, plates and panels regularly to avoid dust build up. Regular cleaning of accessible regions in your air purifier makes for a healthier and happier device.
  3. Make sure that your filters are in good shape. Always check if any of your filters are due for replacement. Remember, clogged filters can worsen air quality, and cause unnecessary damage and overhead to your device.
  4. Regularly service your air purifier. Always follow manufacturer’s labels for detailed instructions on how to clean, maintain, and service your air purifier.
  5. Make sure air purifier has space to breathe. Keep your air purifier in a space that’s open and well ventilated.
  6. Clean all the pre-filters regularly. Pre-filters tend to collect larger bits of dust and dirt, and hence can get clogged pretty quickly. Regular cleaning of the pre-filters will ensure less build up and more efficiency. It will also help you elongate the life of your HEPA and carbon filters.
  7. Make sure that all windows and doors are closed when you turn on your air purifier. Otherwise, your purifier will run on and on, without really being able to cleanse the air inside your room. This will also bring down the efficiency of your air filters.
  8. Make sure that the Ionizing wires and collection blades are regularly inspected for excessive accumulation of dust and debris.
  9. Do not use your air purifier outdoors.
  10. Unplug your air purifier before cleaning any of its internal parts including the ionizing wires and collection blades.
