Best Air Purifier Reviews

Mooka Compact Air Purifier

No products found.

The Mooka Air Purifier is a compact air filter which uses a 20 CFM air sanitation filter. The regular model air filters do not usually help remove harmful toxins in the air; with this type of filter installed you will  have a much cleaner smelling home. It can help eliminate allergens and odors from pets, smoking, and cooking.

Product Highlights

The purifier comes with advanced true HEPA technology. The HEPA filter has three different stages of filtration that has been proven to remove up to 99.97% of harmful particles in the air of up to 0.3 microns. This includes pollen, ragweed, and many other allergens such as mold, dust mites, and cigarette smoke. It’s effortless to use, and you can transport it almost anywhere. This makes the use of a one-button operation to turn it on/off and control the speed of the fan. It’s an elegant and very compact design which means you can place it almost anywhere worrying about it complementing your decor.

For operation, it will circulate and help freshen the area. Bad air usually gets sucked into the bottom of the Mooka; it is then filtered through a multilayer filter, and lastly is ejected out of the air purifier from the top. Thus, fresher air. While in operation, the Mooka will have a whisper-quiet operation; it operates with a noise lower than 60 dB, which will help you rest more at night or not disturb you in your work environment. It’s also affordable to run and a perfect fit for a quiet area.

What’s to like about the Mooka Compact Air Purifier

We love how quiet this purifier works. It’s not often that you will run into a device which follows through with being quiet during operation. We’d have to say that this is one of it’s best features. On the other hand, the design of the Mooka is excellent. It’s easy to use, no complicated methods for cleaning, and it’s very portable. This makes it easier for you to transport it from room to room without hassle.

What’s not to like about the Mooka Compact Air Purifier

This Purifier comes with built-in LED lights. The downside to this is that we don’t like that the light is bright and you can’t turn it off while the machine is in use. That means if you’re used to sleeping in complete darkness, then you’re going to be bothered by the Mooka Purifier.

Product Highlights

This product is best for the earlier times of the year or allergy season.

What’s to like about the Levoit LV-H132 Purifier

Many people want to breathe fresh air, and if you have children, you want the same for them. This unit has a built-in gentle light which you can change up if one is too bright. This is perfect for younger children. It also is operation quiet, which comes in handy when you need to put it in a place where you need it to not make any noise. Lastly, we love that it has an added activated carbon filter, as this can help remove more pollutants and debris from the air.

What’s not to like about the Levoit LV-H132 Purifier

You can change the settings from high, medium, to low. The issues are that we don’t like the fact that this device gets louder at higher settings, which kind of defeats the purpose in the first place. It’s understandable that you should have it on the lowest setting when sleeping, but it would have been nice to see one where you can use the higher settings in relative quiet.

  • Activated carbon filter
  • True HEPA filter
  • 3 speed settings
  • Gentle adjustable night light


  • Short lifespan

Here is a quick buyer’s guide which can help you choose the perfect air purifier for you and your home.

Types of Air Purifiers

Here are a few of the most common air purifiers.


These ones are extremely small and convenient to move, they do not cover a large space though.


These usually need to be installed by a professional and you will find that they are very expensive. They are capable of filtering all the air in your house.

Ion/Ozone Generators

Work for a single room and they work on destroying impurities that cling to surfaces.

Coverage Area

Most air filters will usually cover the extent of one room. Depending on the size of the filter it can cover small, medium, or large rooms. You will need to check the product to get a better idea of how much space it can cover.

Filter Type

HEPA Technology

This type of filter stands for the words High-Efficiency Particulate Air, and it’s a technology that has been common amongst purifiers. They trap at least 99.97% of particles which are larger than 0.3 microns, which means that they are very effective at trapping harmful particles in the air. For a certified HEPA filter, make sure it is a True HEPA filter, otherwise you won’t be filtering 99.97% of the particles. You will see HEPA-type filters, but they lack the extreme filtering capacity of a true HEPA filter

Activated Carbon Technology

This filter type is formed of carbon that is very porous and gives it a very large area for absorption. These were typically found in older models of filters when technology was just starting to become more common in every household. It’s a very effective tool which has high absorbance and can help trap chemical smells and odors.

UV Technology

This technology is used with other filtration systems. It doesn’t get rid of airborne particles, but rather it gets rid of germs and bacteria. While the filter removes particles from the air, UV technology is responsible for destroying the organisms with UV rays. This way you can rest assured that the bacteria in your home aren’t just getting blown back into your home.

Negative Ion

These use chemical injection to help clean the air. It’s an ion which has either a positive or negative charge. These filters are not that advanced and do not work as well. Basically, it cleanses the particle of the opposite charge and prevents those  from going back out and sticking onto your possessions.


These produce the gas ozone which can help get rid of very rough particles using ion technology. However, it is not recommended for use as it is dangerous. The ozone filter can cause asthma to flare up and cause serious damage if you’re being exposed to it for a long period of time.

Energy Usage

Most HEPA purifiers will usually use around 30-250 watts per hour. This depends on the size and how often you keep your air purifier on. If we’re looking in US$, you’d be paying around $39-300 depending on where you live and the amount of usage.

Noise Level

Most air purifiers will produce noise; this is usually unavoidable. You will be able to find quiet technology filters on the market; however, you will have to have them running at the lowest setting.


Most air purifiers offer a 3-year manufacturer’s warranty which will cover any damages or errors on the part of the manufacturer. If you break the unit, it will not be covered in the warranty.


What Does An Air Purifier Do?

An air purifier can help filter out various types of bacteria, and particles that aren’t healthy for you to be breathing on a regular basis. Some of these include dander from pets, chemicals from products, fungi, dust mites, mold, viruses, etc. The air filter will suck the air into the purifier and filter or destroy the particles that are harmful to you.

How To Reduce Air Contaminants in a Room?

You should get an air filter which can cover the entire room. If you aren’t using a filter, then other ways are to air out the room by either leaving the door open or opening a window. This can help reduce the number of germs and bacteria that stay in the room.

How To Use An Air Purifier

Simply remove the unit from the box, and make sure the filters are in place. Then, plug the air purifier into a wall outlet. Let it work for the next few days and then check the filter inside; it should have a small buildup of dust and other particles.

How to Choose An Air Purifier

If you’re in the market to buy one, then we highly suggest knowing what type of air purifier you’re going to want in your home. Some people can get away without having dual or triple filtration systems. However, others may need these systems. Be sure to do your research about purifiers and filters, and then you can go ahead and choose one based off of all the other extra factors.

How to Clean Honeywell Air Purifier Filters

Open up the machine and check if the filter tray has any particles or dust on it. Sometimes these things can’t be seen with the naked eye, but you can usually tell that the color has changed. Wipe down any parts that are dirty, or make sure to install new filters. Always let them air dry if you choose to opt for washing them yourself. Put the lid back on, and you should be good to go.


As you can see, it’s not hard to choose an air purifier, just a little confusing. You just need  the right information. If we were to suggest the best buy air purifier, it would have to be the Germ Guardian. There are so many wonderful features, but you can refer back to the product’s review if you need more information.
