  • How to use and operate an air purifier
  • How to maintain an air purifier

Read on and you will know everything there is to know about air purifiers.


How to Use Air Purifier Properly

Follow the simple steps below when using and operating an air purifier.

1. When choosing the right spot for your air purifier, check on the air vents and make sure that air can easily go in and out of the device. So, if the air output vent is located at the back of the unit, don’t place its back near the wall.

2. If you have already chosen the perfect spot for your air purifier, plug it in and turn the unit on.

3. Customize the fan speed (if different settings are available) according to your needs. Use the guide below:

  • Low fan speed – this is the lowest and quietest setting. Use it during bedtime and when minimal air purification is required.
  • Medium fan speed – this setting is for normal usage and is great for maintaining indoor air quality that’s already good.
  • High fan speed – high speed is best used when immediate air purification is needed (such as when there’s a smoker in the house).

4. Use the Remote Control (if available) for convenience – you can change the settings on your air purifier even from afar.

5. Turn the air purifier off when not needed – although it’s advisable to always keep it running to maintain good air quality at home, you can turn it off once in a while.

How Does an Air Purifier Work?

If you’re not very familiar with air purifiers, you’re surely wondering how they work. Well, there are 5 basic types of air purifiers and filters and they all work (and perform differently).

In this section of this post, I will cover how the following types of filters work in purifying the air:

HEPA Filter

Most air purifiers use HEPA filters as the main filtering system. Its design includes an in and out airflow wherein dirty air is sucked in and filtered (or purified) before being released back into the environment as clean air.

Since it comes with a very fine filter, allergens, dust, and other airborne particles are trapped in the filtering system permanently. With a True HEPA filter, its efficiency rate can be as high as 99.97% and the filter is capable of catching very small particles (up to 0.3 microns in size).

Other types of filters and HEPA-type filters are also good but only have an efficiency rating of about 99% (and can only filter particles that are bigger in size).

Carbon Filter

A Carbon filter is usually used in conjunction with a HEPA filter. As the pre-filter to the main HEPA filter, it works by protecting the HEPA filter and extending its life in the process. Particles will first pass through it, and those that are trapped will no longer reach the HEPA filter.

Using carbon mineral in its design and structure, a carbon-based filter is very effective in absorbing odor, gaseous substances, and smoke.

Permanent Pre-Filter

Usually included in an air purifier’s design (and usually washable), a pre-filter acts as the first line of defense in filtering the air from impurities. This filter is capable of blocking large particles of pollutants like pet hair, dust, and dirt.


Using an ionizer is really simple because it comes with a simple design. Since it works by releasing negative ions into the air, all you really need to do is turn the unit on.

If an ionizer feature is included in an air purifier’s design as a complementary feature (and not as the main air purifier), it usually comes with its own control system. You can, therefore, turn it on and off as needed.

UV Light Technology

A UV light air filter is another type of air purifier that has a simple design. If the air purifier is mainly a UV light air filter, all you need to do is turn it on. It will then purify the air by sucking in air contaminants (germs), exposing them to the radiation of UV light, and releasing clean air back into the environment.

A UV light feature can also come included in an air purifier with another type of air filtering system. If this is the case, a separate control is usually provided for controlling the UV light functionality – it will have its own on/ off control.

Ozone Generator

An ozone generator works by producing ozone (which is a toxic gas). If the air purifier is mainly an ozone generator, it is only recommended for shock treatments and people (and animals) should leave the place during the treatment.

If an air purifier merely includes an ozone generator as an added feature in its air filtering design, it will have its own control system. You can, therefore, turn it on and off as needed – but keep in mind that exposure to ozone is dangerous to your health (since it’s a toxic gas).?

How to Maintain Your Air Purifier

This portion will guide you as to the steps involved in cleaning your air purifier. It will cover all types of air purifiers mentioned above, such as:

HEPA Filter

Follow these steps when cleaning and maintaining your HEPA air purifier:

  • Remove the filter.
  • If the filter is disposable and already dirty, change it immediately.
  • If the filter is washable, you can either vacuum it to clean it or wash it with mild soap and water.

Carbon Filter

If your air purifier’s carbon filter is already dirty, follow the steps below.

  • Remove the filter from the unit.
  • If the filter is permanent and plastic-based, you can wash it with mild soap and warm water.
  • If the filter is disposable and replaceable, get a new one when it’s already dirty and clogged up.


To clean and maintain your air purifier’s pre-filter. Perform the following steps:

  • Assuming that it’s a permanent filter, remove it and wash it.
  • Allow the filter to be completely dry before returning it to the device.


An ionizer doesn’t have a filter, but dust can accumulate inside the air purifier. Clean it by following the steps listed below.

  • Open the unit’s chamber and brush off the dust from the surfaces inside (do this outside the house).
  • You can clean the fan by wiping it with a soft damp cloth.
  • If there’s a blade system, you can wash it if it’s removable. Otherwise, you can simply wipe it with a damp cloth or a microfiber cloth.

UV Light Technology



Since a UV light air purifier doesn’t carry a filter, there’s no filter to clean and change. However, you can still clean it and maintain its efficiency by doing the following:

  • Open the unit’s chamber and clean the insides with a soft bristled brush.
  • Make sure that the unit is dust-free both inside and out.

Ozone Generator

An ozone generator type of air purifier doesn’t use a filter – so again, there’s no filter to maintain. However, you need to clean its air purification system by following the steps below.

  • Remove the ozone plate by pulling or ejecting it from the device.
  • Wash the ozone plate with hot water.
  • Allow the ozone plate to completely dry before installing it back into the air purifier.

Which Air Purifier and Air Filtering System Should You Choose?

I highly recommend a HEPA air purifier because it’s the most efficient of all types of air purifiers today. It will be particularly useful to you if you want to purify your indoor environment from the following pollutants:

Clean Dust

  • Dust
  • Dust Mites
  • Pet Hair
  • Pet Dander
  • Pollen
  • Mold Spores
  • Other Airborne particles (even microscopic elements)

You can also go for an air purifier with a Carbon Filter if you’re looking for a solution for the following:

  • Smoke – cigarette smoke, cooking smoke, etc.
  • Odors – all types of odors (cooking odors, smoke odors, food odors, etc.)
  • VOCs such as the chemical fumes released when you use household cleansers.
  • Chemical emissions (such as formaldehyde – which are found in carpets, upholstery, wood paneling, etc.)

I would also recommend an ionizer if you’re dealing with the following:

  • Dust
  • Pollen
  • Odors
  • Smoke

A UV Light air purifier is also highly recommendable for the following purposes (remember that it can kill germs):

An overloaded residential dumpster full of trash

  • For sanitation
  • For disinfection
  • For deodorization

While I really don’t recommend using an ozone generator (because it’s a toxic gas), I still think its usable for shock treatments for highly contaminated areas. You can use it for the following:

  • To kill germs
  • To deodorize

All in all – my personal preference would be an air purifier that uses a HEPA and Carbon filter combination. However, it would be good to get those models that include the other types of air filters as long as these features come with their own on/ off control system.

So, there – you now know how to use an air purifier and how to maintain it as well. You even know how to choose the right model for your now. Do let me know how it all turns out for you by leaving a message in the comment section below. And don’t forget to share this article with your friends, ok?
