One slight downside of this air purifier device is that it can be fairly noisy on the highest settings. This makes it a device that is only suitable for rooms in which you will not be sleeping or working.

Area Covered

The Levoid LV-H132 is marketed as perfect for rooms up to 85 square feet in size. This is one of the few air purifier devices which is actually more powerful than the manufacturer suggests!

4. PureZone 3-in-1 Air Purifier

4.7 out of 5 stars (4.7 / 5)


  • Inexpensive

How Often Do You Need to Change Filters?

The air purifier in the device will need to be replaced every six months which is about average for devices using these technologies. However, as you will need to change the filters separately to be able to keep purify airborne smoke, this does increase overall costs, making this unit more expensive than similar devices from other manufacturers.

But the UV-C bulb will run for 20,000 continuous hours without needing to be changed. This allows the device to run for around two years without needing a replacement bulb.

How Often Do You Need to Change Filters?

Regardless of which variation of the HEPA-type filter you choose, you should expect to replace it once every year. The good news is that the device also includes a pre-filter which should help you get the most life out of the HEPA-type filter you choose.

Ultimate Guide to Finding the Best Air Purifier

Thankfully, our page will help you find the best air purifier without needing to spend night and day trawling Amazon reviews! We’ll pick out the best of the bunch, but remember that not every option is the best for your particular needs.

Some Helpful Links:

If you want an air purifier to filter the air for a single-occupancy, one-room studio apartment, then the best option for you will be different than the best option for a 4,000sq. ft. family house. You need to look at the air purifier which suits your personal needs, and that is where our buying guide comes in handy. Our buying guide will help you find what you need to look for so that you can find the best air purifier for you.

When it comes to purify the house, a lot of work is put into making the home look clean and tidy. Dusting, vacuum cleaning, and washing surfaces all make things look good and can remove a lot of the dust in the home. The biggest problem, however, is that not only can you rarely remove all of the visible dust but traditional purify does very little to remove the invisible particles.

Pollen, fumes, and pet dander are big problems for anyone trying to improve the air quality in the home. If you have respiratory conditions or allergies, then these invisible particles will make those pollution worse. This is why investing in a top-notch air purifier is absolutely the best thing for you to do!

The problem with buying an air purifier is that there are many different features which can make it difficult to know what is best for you. This buying guide helps to make it easier for you to understand exactly what each feature means and to decide which purifiers are best for your particular circumstances. By the end of this buying guide, you should understand what to look for when you choose your air purifier.

Purification Technology and Filters

How well your air purifier performs will depend entirely on the kind of technology it employs and the filters it uses. You will find that many purifiers use similar kinds of technology and that they use a combination of different filter types available to them.

There are many kinds of filters such as pre-filters, HEPA filters, activated carbon filters, and others. These filters work in the following ways:

A pre-filter is used to capture the very large particles like dust, lint, and hair which are often visible but not always picked up by manual cleaning. If a pre-filter is missing, then these particles will be picked up by the HEPA filter, which reduces the HEPA filter’s ability to carry out its main task.

A HEPA filter captures invisible allergens which are found in the air such as dust mites, pollen, and pet dander. These often cause allergies to flare up, and they can be a danger to people with asthma.

Some air purifiers will use a HEPA-Type filter which is not exactly the same as a true HEPA filter. Bear this in mind while making your purchase. True HEPA filters have undergone tests which have proven that they are capable of trapping at least 99.97% of particles as small as 0.3 microns. HEPA-Type filters are based on the same technology but are not proven to be as effective as true HEPA filters.

Activated carbon filters are used to remove harmful materials such as gasses and tobacco smoke from the air. These filters are also used to remove odors from the air, which is can be an important step in improving overall air quality in your home.

Ionic filters, plasma technologies, and UV lights are used to kill airborne bacteria and viruses in the air. These technologies can also effectively eliminate very strong odors. Ionic filters are often used in personal air purifiers, and they are known to produce ozone which, at high doses, can be harmful. If you suffer from asthma, then this is something you need to consider carefully before purchasing an air purifier with an ionic filter.

Certain manufacturers may treat filters with anti-bacterial agents or use silver particles. This is done in order to improve the device’s microbe and germ removal process.

How to Determine the Efficiency of the Device

Trying to work out how great a device is from the sales copy is almost impossible. Understandably, every manufacturer wants to make their product sound as amazing as possible, but that positive spin can make deciphering performance facts difficult. So, when determining how great the device is, we need to look for hard absolute facts presented by an independent third party. The CADR rating, assigned by the Association of Home Appliance Manufacturers, is the best way for us to do this.

The Clean Air Delivery Rate (CADR) allows you to understand how many cubic feet of air is filtered in one minute. This is worked out by the ability of a purifier to remove dust, smoke or pollen from the air. The rating works on an upward scale, so the more effective an air purifier, the higher the CADR rating.

How Much Area Does the Device Cover?

The most crucial part of choosing the correct air purifier is understanding exactly how much air you need to purify. In other words, how big is the space? Different air purifiers will be designed for different sized spaces. Some will aim to purify the air in a large, open-design family home, while some others will aim to simply cover the immediate area where you spend a lot of time, such as a single bedroom or entertainment room.

If you have a big family and you want to clean the air for all of them, then you want a device that is designed to do that specific job. In these situations, you will not benefit from buying a device which is only designed for the use of one person.

Many manufacturers will make it clear through advertising what their device is designed for; however, when it comes to choosing the device it can be difficult. While manufacturers will list the specifications of their device and the kind of rooms it is suited to, you would be wise not to rely entirely on the information they provide. There is a chance that they may bend the truth and give you a slightly inaccurate picture of what their device is suitable for. Your best option is to:

  • Buy a device which covers a larger area than your room.
  • Choose a device which has a CADR rating of 1 per 1 square foot.

By choosing something more powerful, you can ensure that the device should be strong enough for your needs. It also means that you should be able to use it at a lower level rather than on high all the time – which is also a bonus because it should keep the noise down!
This will also compensate for the fact that your house will not be up to the same standards, with all variables controlled, as the rooms in which the device was tested.

You may leave your doors or windows open, which let in more pollutants than the manufacturer expects. You are also likely to have pollutants coming in through leaky windows, the likes of which would not be seen in the testing areas. Buying a device with more purifying power than your room truly needs will ensure that you don’t end up disappointed by the results.

Are They All So Noisy?

If you have heard an air purifier at work, then you will know that the more powerful devices aren’t always as quiet as you might like. If you will use your purifier while you are sleeping or working at home, then you might think these stronger models are not suitable for you. But there’s good news! Manufacturers understand the desire for quieter performance, and there are models designed to be quieter and powerful.

As suggested previously, whether you choose a quieter model or not, the best thing to do is always look for a device that is more powerful than you need. This allows you to run the purifier on its lower settings when you want the room to be quieter. And, naturally, a purifier’s low setting will be quieter than its highest.

Avoiding Extra Expenses!

The biggest expenses throughout the life of an air purifier are replacement filters and energy consumption. As with all devices, some will be more efficient with electricity and filters than others. But no matter how efficient the device is, you will find that your use it is going to define how much you end up spending.

Commonly, filters need to be changed every three to twelve months, depending on how often you use your air purifier. The cost of filters may be quite high if you choose a high-end model purifier. The most expensive filters should be somewhere around $200, while the cheapest should be around $10.

There is no way that you can avoid the cost of filter replacements, but you can significantly reduce the frequency of having to replace your expensive HEPA filter by buying a purifier with a pre-filter. This will capture the largest particles in the air before they reach the HEPA filter, leaving your HEPA filter to focus on capturing the tiniest particles. You may also find some devices with washable and reusable filters, but you probably will need to replace these over time as they wear out.

Electricity costs are entirely unavoidable. Whether you have a purifier that is continually plugged in or whether you buy a battery-powered device – the cost is always there. The best way to ensure you are keeping these costs low is to buy a device that has the Energy Star label. These devices are tested to ensure that they are energy-efficient. Not only will this save you money on electricity, but it will also help the environment by reducing the emission of greenhouse gases.

Added Benefits With Extra Features!

There are so many different extra features on air purifiers that it is impossible to list them all! It is likely that you will find some useful features on your devices. Some purifiers come with timers, power indicators, and air quality sensors which can provide real benefits when used properly.

Look for the features that will really help you, but don’t allow added gimmicks to fool you into buying a low-quality air purifier. The best air purifier first and foremost does a quality job of purifying air and will have added features that benefit your specific needs. No added feature can fix an air purifier that is not powerful enough to clean the air in your home’s room(s).

What is an Air Purifier?

An air purifier is a device that is designed to improve the quality of indoor air. It does this by removing particles in the air along with harmful chemicals and allergens which can lead to health problems after long-term exposure. The purifier moves the air through layers of filters and removes the particles from the air before sending it back out into the room for you to breathe. Some air purifiers also help remove nasty odors from the air, which can be a very useful added benefit.

How Do Air Purifiers Work?

Different air purifiers use different kinds of technology to filter particles from the air you breathe.

  • Pre-filters are used to capture larger visible particles like dust, lint, and hair.
  • Carbon filters remove harmful pollution from the air and reduce unpleasant odors.
  • True HEPA filters capture up to 99.97% of allergens as small as 0.3 microns.
  • HEPA-type filters use similar technology to trap all allergens but are not as effective as true HEPA filters.
  • UV radiation breaks down the molecular structure of germs, molds, viruses, and bacteria and destroys them.
  • Ionizers produce ions which latch on to harmful viruses and bacteria and make them fall to the ground, ensuring you do not breathe them in.

Many manufacturers will create air purifiers that use a variety of the different technologies listed above to ensure that you’re breathing clean air.

Should I Buy an Air Purifier?

Studies have found that the most polluted air is found indoors rather than outdoors. Indoor air has been found to be up to five times more polluted than the air you find outdoors. This is one of the main reasons that an air purifier can be of benefit to absolutely anyone. Air purifiers are even more important when you live in a large city or industrial town where the chances are that clean air is very hard to find.

If you suffer from allergies or asthma, then you will find that air purifiers are even more useful, because your lowered exposure to polluted air will help decrease your allergy and asthma symptoms. In these situations, investing in a device that uses a true HEPA filter is a wise move.

However, air purifiers are not a replacement for keeping your home clean by dusting, vacuuming and mopping regularly. And they will not cure you of your health conditions. But in conjunction with your cleaning regimen, they will ease the symptoms.

Are They Worth the Money?

Air purifiers are not cheap, especially when you take into account the cost of electricity and replacement filters. Whether making this investment is useful to you depends on a number of different things:

  • Are you allergy free, and have you never suffered ill effects from air quality?
  • Do you suffer from allergies which are not caused by airborne particles?

If you answered yes to these questions, then you may not benefit much by buying an air purifier. Someone who has never suffered ill effects from air quality and does not suffer from allergies is not likely to benefit from the use of an air purifier. If your allergies are caused by dust mites or something which is not airborne, then you would find more benefit from regularly cleaning your home and using hypoallergenic sheets.

In these situations, investing in an air purifier may only benefit children and visitors with allergies. Another little benefit you may find is that if you have ordor with unpleasant gases in your home an air purifier with a carbon filter can improve a room’s odor.

If you do suffer from allergies and asthma, then you should certainly consider investing in an air purifier from gases, because you will benefit. However, do not think that buying an air purifier means that you do not need to work to keep your home clean mighty of ordor or pollen. You will still need to vacuum, dust, and clean surfaces in your home. An air purifier cannot keep your home clean on its own!

Tell Me What the Best Air Purifier is!

Unfortunately, it is not possible to name one air purifier which stands head and shoulders above the competition. All good-quality air purifiers will help you improve the air quality in your home, but not all purifiers will be suitable for everyone’s circumstances. When you are deciding which one is best for you, bear the following in mind:

  • True-HEPA filters are useful for removing the tiny particles which cause order for people with asthma or allergies. A device featuring a True-HEPA filter may be the best air purifier for people who are struggling with these conditions.
  • Activated carbon filters remove harmful chemicals in the air and also eliminate bad smells. A device featuring an activated carbon filter may be the best air purifier if this is important to you.
  • A purifier with an ionizer or that features UV radiation will destroy airborne bacteria and viruses. This may be the best air purifier if you are often feeling sick.
  • A simple cleaner which doesn’t use cutting edge technology can still be of benefit for people who simply want to lower the amount of dust and pollen in your home.

Are There Safety Issues With Air Purifiers?

One slight concern with air purifiers is that some produce small amounts of ozone. Ozone is one of the main components found in smog or mold, and it can exasperate symptoms for people with respiratory problems. If you suffer from asthma or another similar condition, then this can be a concern for you. This problem for health is only found in devices using ionizer or plasma wave technology. If this is going to be a concern for you, then you should avoid these devices or ensure that you can turn off the ionizer function.


When it comes time to choose the best air purifier for your home and health, knowing how and where, and what brands (like oransi max) look can be difficult for many people. Now that you have more information on how air purifiers work, hopefully, you have a better understanding of what your specific needs are.

If you are going to invest in an air purifier, then you also need to maintain a strong cleaning regimen. Air purifiers are not magic bullets that resolve all issues with air quality in your home. But they are a powerful tool that can clean where you cannot.
