8 Best Rated Filterless Air Purifiers for Clean Air Indoors

K eeping clean air at home should be a top priority for every homeowner who is interested in having a welcoming and healthy living environment. In this matter, an air purifier is the best ally as it tends to impurity removal from the air to help you breathe easy and maintain good health.

As pointed out in a study by the World Health Organization, approximately 3.8 million people per year die from illnesses related to indoor air pollution. This number alone shows that air quality improvement is no joking matter. Air cleaning systems are a necessity, especially in households where solid use and kerosene are used for cooking. The same goes for people living in industrial areas, where air purity is a serious issue both indoors and outdoors. Opening the windows to let in fresh, clean air is not viable in these cases.

However, there are many variants of air purification systems out there, and if you seek one that isn’t only effective in its performance but that is cheap to maintain, the filterless air purifier is what we recommend because, as the name suggests, there are no actual filters to replace with it. If you are curious to learn more about this intriguing device and take an in-depth look at what the market has best to offer, check out the following reviews. Before we jump to the reviews though, let’s first learn how these systems work since this might help you decide on specific models later on.

How Does a Filterless Air Purifier Work

The only considerable difference between filter and filter-free systems is that filter-free units are much cheaper in the long run as there are no purification media to replace. Filters like HEPA cost a considerable amount of money. So, if you’re on a budget but you want to breathe fresh and clean air, filterless is the right choice.

They are simpler to maintain as all you need to do is clean them occasionally through vacuuming or wiping them with a damp cloth, contingent on the situation. When it comes to variants, you have:

• Air Ionizers – The two plates integrated are electrically charged to sanitize the air. The electrical field charges the contaminants inside and clean air is released into the room. Furthermore, the other plate works similarly to a magnet. It will attract smaller contaminants and charge them. Hence, every small allergen in the room will be trapped and neutralized.
• Electrostatic Precipitators – If you have a small living space, you will find this type helpful as it is highly efficient at removing contaminants within an enclosed space. If you open it, you will see several wires and plates that work together to make a high-voltage electrostatic field.
• Ultraviolet Purifiers – Powerful at removing microorganisms that are harmful to your health. This is why you will see several purifiers with filters with UV technology built-in. Best of all, they’re not only highly effective but also cost-efficient.

In the majority of cases, customers feel comfortable running them day and night as the noise produced is minimal. Generally employing a 3-stage purification process, these models can be able to collect allergens down to 0.1 microns, including smoke and dust. Additionally, you will no longer need to use air fresheners as the majority of models are designed with optional ionizers.

Now that you are aware of how these products work, let’s move on and see what your best options are and what makes them so great.

2. Airfree Lotus

Check Price at Amazon

Summary: An Airfree product that you are bound to appreciate for its high air pollutant removal rate of 99.9%, the Lotus might be powerful but it doesn’t take up much space, which is a plus. Best of all, it is completely silent operation makes it perfect for the nursery or bedroom.

---

Thermodynamic TSSTM Technology

This technology uses heat which is similar to boiling water temperatures to destroy 100% of all micro-organisms. Inside, the temperatures can reach up to 400 degrees Fahrenheit. Hence, all viruses, bacteria, mold spores, or contaminants that are affecting the immune system will be destroyed.

The same technology is used by other Airfree filterless air cleaners that are almost equal to the upgraded version we reviewed here when it comes to performance. Models like the Airfree Onix 3000, the Airfree P1000, the Airfree Tulip, and the Airfree T800 are also worth considering, hands down. The Onix 3000 is fairly similar to the Lotus, and it even caters to same-size spaces of 650 square feet. If it’s a small space that you need air purification for, the T800 that works for spaces of up to 180 square feet is the option you are better off with. If, however, the area you need the device for stands at around 450 square feet in size, the Tulip and the P1000 are your best options.

3. Air Oasis 1000 G3

Check Price at Amazon

Summary: Using ionization and AHPCO technology, the Air Oasis breaks down pollutants to make the air indoors safe to breathe even for asthma sufferers. It might not be the best option for getting rid of foul smells, but this won’t be an issue if you didn’t intend to use it in a room like the kitchen anyway.

---

Among the top choices of customers is the G3 model coming from Air Oasis that can handle rooms as large as 300 square feet. It’s a tower purifier made of aluminum and polymers that bring a classy touch to your home. The manufacturer offers a generous lifetime warranty for this highly efficient system. The sole maintenance task that is required for you to perform with time is to replace the AHCPO cell every 3 years or so (the system notifies you when the exact time comes).

Innovative

It uses two innovative technologies, namely a photo-catalytic UV lamp that kills carbon-based particles, and a Bi-Polar ionization technology that releases ions to eliminate impurities from the air. Additional characteristics are:

• Its operating relies on an Advanced Hydration Photo Catalytic Oxidation(AHCPO) that basically neutralizes carbon-based particles and uses hydro-peroxides to disinfect the air

• Flaunts a one-button control that makes it intuitive to use
• Removes up to 99% of aeroallergens, VOCs, odors, and microorganisms

Design

It measures 4” x 4” x 14.13” and it only weighs 6 pounds. This means that you can take it with you wherever you go. Its ozone output is 0.05 parts per million which means that it’s not harmful to our health. The positive to negative ion concentration is 20,000,000 cm3.

The greatest thing about it is that it doesn’t affect your energy bill regardless of how often you use it. This is because it only uses 15 watts. If you use it daily for 4 hours continuously, it won’t cost more than a coffee at Starbucks. Furthermore, it is made from anodized brushed aluminum and polymers.

4. Ivation Ozone Air Purifier

Summary: A product that differs from the rest of our picks, this Ivation unit is actually an ozone generator. If your main issue is dealing with unpleasant smells, this is your go-to, hands down. It’s effective when it comes to removing dust, pollen, and allergens too, but it doesn’t fare as well as the other products we reviewed from this point of view.

---

Wondering why the stats for this Ivation filterless air cleaner differ so much from the other entries on our list? This is actually an ozone generator, one of the best there is for sale at the moment. It is indeed a filter-free unit, so there’s no cost involved with changing filter media. However, the downside with it, and it’s a major one too, is that it produces ozone in its operation (evidently!).

Ozone Output

It outputs 360 milligrams of ozone per hour, so if you suffer from asthma, stay away from this product because it will cause your symptoms to act up. It’s not safe to use in a nursery or child’s room either, and when it runs, you should leave the room and return at least 30-60 minutes after it has finished for the ozone to clear.

Large Area Coverage

If you are fine with all of the aspects we just mentioned, however, this is one of the best filterless options available, especially if you intend to use it for a large space. It covers areas up to 3,500 square feet, in fact, so you can see why we recommend it for attics, basements, large living rooms, and areas of the sort. On the downside, it is more of a deodorizer than a full-on air purifier.

It tackles removing odors unlike any of the products we reviewed here, but when it comes to air pollution reduction, it has a lower efficiency than models like the Airocide APS-300, scoring only 95%. However, it does fare well when it comes to removing pollen and dust, so if you are allergic to these specific pollutants, it might just be what you need.

The TA500 is yet another example of excellence on the company’s part since it clears the air of impurities at the fraction of the cost other products do. It even draws an insignificant amount of power when it runs (12 watts) to ensure the bills won’t get amped too much by its presence.

Aside from the fact that backing from defects is granted for 1 year, which is pretty standard for this niche, there’s another aspect that puts your mind at peace when it comes to the product’s quality. That is the fact that it’s an Envion model, evidently. The company is quite renowned for the performance and durability of the air purification systems it releases, as well as the approachable price it sells its products for.

8. GermGuardian GG1000

Check Price at Amazon

Summary: Perfect for the small spaces in your home like closets or the bathroom, the GermGuardian is a cheap yet reliable air purification system.

Here, we want to briefly present the alternative options that you also ought to look into before you decide since one of them might suit your expectations better.

Filter Vs. Filterless Air Purifier

Every time you encounter a different and more intriguing device, it’s natural to be skeptical until you learn more about it. If filter purifiers never made you question their efficiency because you were familiar with their operation, things could get tricky with filterless models. To help you make up your mind between the two, let’s draw a quick comparison.

Efficiency

In terms of efficiency, the two types provide similar results, so you won’t regret choosing any of the two. While one uses a filter to capture air impurities, the other is based on physics to reach the same purpose. However, HEPA systems are more effective in eliminating a wider range of impurities, which is where their vaster popularity spans from. Moreover, they are more suitable for people with allergies as they target dust mites and manage to retain more particles.

Maintenance

For some customers, maintenance is the most important aspect to look into as they don’t want to waste much time or money on catering to the system’s needs. This is where filter-free models reign as they only require occasional cleaning via vacuuming or using a damp cloth, whereas classic systems need their filters replaced routinely, aside from requiring cleaning as well.

Costs

By far, the smartest option cost-wise is the filterless system as, upfront, it doesn’t differ much in terms of pricing (some models are even cheaper than their classic counterparts), and it doesn’t require any investment down the road as there are no filter media to replace.

---

Allergy Triggers

To relieve yourself from allergies, you have to change the way you live and your choices. Numerous things around your home can act as a trigger, and it is the purpose of the purifier to tackle these contaminants so your allergies won’t act up anymore, eliminating them from the air.

Dust Mites

It is among the most common indoor pollutants and a leading cause of asthma in children. Your home environment is the perfect area for them to grow and multiply. They enjoy temperatures that are above 75 degrees Fahrenheit and humidity from 75% to 80%. If the humidity falls below 50%, they will simply die.

Dust mites are found in pillows, mattresses, carpeting, and upholstered furniture. To minimize them you have to remove any curtains and drapes in the bedroom and keep pets out of the area where you sleep. You should also wash bed linens frequently in hot water and keep humidity low.

Pollen

If you’re suffering from allergies, you know how dangerous pollen is for the symptoms of this health condition and how difficult it is to avoid entering into contact with it as well. Different people can be allergic to different types of pollen. It’s inevitable for your home to have pollen particles because it comes from everywhere.

You should opt for wood flooring as it is much easier to clean. You should also wear a mask when you clean the house. Evidently, using an air purifier is advised since it effectively removes pollen, being imperious to run during spring when pollen pollution is at its highest.

Mold

This is a fungus that causes spores that float in the air. If a person comes in contact with a large amount, there are dreadful repercussions. As a rule of thumb, you have to remember that there are different kinds of mold, some that are visible to the naked eye and others that aren’t.

Frequently Asked Questions

Do filterless air purifiers really work?

When it comes to their efficiency in air pollution decrease, filterless models are fairly hard to top. While they might not rely on HEPA and other types of filters, this does not take away from their effectiveness. Needless to say, it’s the specific lack of filters that makes them even more appealing since long-time operational costs are reduced because you won’t have expensive upkeep tasks to worry your mind with. The only issue is that some models produce ozone when they run, but as long as the stats are within safe parameters, there’s no need for concern.

Is inhaling ionized air safe?

There is no actual danger associated with inhalation or exposure to negative ions for humans. However, the ozone that filter-free air purifiers produce can be an issue if the amount is not within safe parameters (0.05 parts per million tops).

Can air purifiers destroy viruses?

Yes, they do significantly reduce viruses, germs, and bacteria. Units that feature UV light sterilization are even more efficient from this specific point of view since the technology focuses on destroying microorganisms.

Should I sleep with the air purifier on?

As long as the unit you use doesn’t produce high traces of ozone (0.05 PPM tops), then it’s perfectly safe to run it during the night, while you sleep. You ought to look for a model that is as quiet as possible so that it won’t distract you during your nocturnal slumber.

Are UV air purifiers superior to their regular counterparts?

Since UV technology is the best at annihilating bacteria, viruses, and germs, it’s safe to say that UV air purifiers are indeed superior to their classic filter counterparts since they provide thorough air sterilization. Moreover, they are better when it comes to energy efficiency as well.

Do air purifiers consume a lot of electricity?

Most models don’t consume more than 50 watts when they run, so you shouldn’t worry about running costs in the slightest. These devices are generally known for their low power draw, and with some of the models we presented here that consume less than 20 watts, even running them 24/7 won’t amp the bills.

---
