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 how they worked, things could get tricky with filterless models. A quick comparison of the two will help you discover which one is best for you.


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 purifiers have proven to be more effective in eliminating a wider range of impurities, which is why they are more popular. Also, they are more suitable for people with allergies because they target dust mites and manage to retain more particles from the air.


For some customers, the lack of maintenance is a key feature of filterless purifiers so they opt for this type to eliminate the need to buy and replace filters. This also means that the long-term costs are reduced and there are fewer chances of getting into contact with the dust and debris while cleaning or replacing the filter. Still, the operation of the filterless model is intriguing for many so they prefer going for the regular purifiers or the models with a washable filter.


Whilst the initial cost for a purifier without a filter is higher when compared to the normal ones, you will find that as time passes this turns into an investment. Over time, you will get your money back. The reason why we are highlighting this is that with the usual purifiers, you will have to change the filter every 3 months in order to maintain the same efficiency. Whereas, with a filterless model, all that you will have to do is to clean it.

Filterless Purifier Buying Guide Image

Allergy Triggers

In order to relieve yourself from allergies, you have to change the way you live and your choices. There are numerous things around your home that can act as a trigger rather than your helping hand. This is why you need to purchase a filter. They are so powerful that they will be able to deal with any possible triggers. In fact, there are no triggers that don’t get eliminated by the purifiers. Below you will find a list of the things that can make you sneeze, have a runny nose, red and itchy eyes, wheeze, and itch.

Dust Mites

This is one of the most common triggers that you will find in any household. It’s actually one of the main causes 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 a humidity between 75% to 80%. If the humidity falls below 50% they will simply die.

You can find them in your pillows, mattresses, carpeting, and upholstered furniture. It doesn’t necessarily mean that your house is dirty if you have them. In fact, when you vacuum, they float in the air and settle once you are done.

To minimize them you have to remove any curtains and drapes in the bedroom and keep pets out of the area where you sleep. In addition to this, wash bed linens frequently in hot water and keep humidity low. In order to eliminate them completely, you will need the help of a purifier.


If you’re suffering from allergies since you’re young, you may already know that pollen is found everywhere as it comes from trees, grass, flowers, and weeds. 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. We are surrounded by it.

In order to manage the number of pollen particles in your home, you need to opt for wood flooring. This is because they are much easier to clean. In addition to this, we recommend that you wear a mask when you thoroughly clean your home. Likewise, with dust mites, it’s best that you keep a purifier in your living room and bedroom especially during spring. That’s when the dust particles double.


You may be already aware that this is a fungus which causes spores that float in the air. If a person comes in contact with a large amount of them, there are dreadful repercussions. Dust allergies may be the least painful one to deal with. As a rule of thumb, you have to remember that there are different kinds of mold. Some you can see and some you don’t.

It’s worthy to mention that mold lives everywhere. This includes fallen tree leaves and your home. Places like your bathroom, kitchen, and bedroom. We strongly advise that you seek the help of a specialist to get rid of it completely. Meanwhile, you need an air filter that will suck up those spores way before they get to you.

How Does A Filterless Air Purifier Work

Similarly, to the purifiers with filters, these units will remove the contaminants in the air. The only considerable difference between the two is the fact that you don’t have to spend further money to replace the filters every few months. As you may have noticed, filters such as HEPA are a considerable amount of money. So, if you’re on a budget but you want to breathe fresh and clean air, filterless purifiers are the right choice.

It’s incredibly easy to maintain such a unit. Just because there isn’t a filter it doesn’t mean that you will spend a lot of time cleaning. All that you will need to do is to vacuum the inside of the purifier and clean it with a damp cloth if that’s the case. There are several kinds of filterless purifiers that you can choose from:

  • Air Ionizers – The two plates integrated into the unit are electrically charged to sanitize the air. The electrical field will charge the contaminants inside of the purifier and clean air is released back into the room. Furthermore, the other plate works similarly to a magnet. It will attract smaller contaminants to itself and it also charges them. Hence, every small allergen in the room will be trapped and neutralized. An example of such product is LightAir IonFlow Evolution 50. As you can see from the review, it also has an energy-efficient operation.
  • Electrostatic Precipitators – If you have a small living space, you will find this type helpful as they are highly efficient at removing contaminants within an enclosed space. If you open such a purifier you will see a number of wires and plates that work together to make a high-voltage electrostatic field.
  • Ultraviolet Purifiers – Similarly, to the other types, these units are highly powerful at removing microorganisms that are harmful to your health. This is why you will see a number of purifiers with filters with UV technology built within them. Best of all, they’re not only highly effective but also cost-efficient.

In the majority of cases, customers feel comfortable to run the purifier throughout the day and night as they produce minimal noise. Nonetheless, this doesn’t mean that they’re any less efficient. In fact, many of the models mentioned in this review have more than 3 stages of filtration. Hence, they are capable of removing allergens as small as 0.1 microns. This includes dust, pet dander, and smoke. Additionally, you will no longer need to use air fresheners as the majority of them are designed with optional ionizers.

Features To Consider When Choosing a Filterless Purifier

There are many advantages that you can benefit from if you choose such a purifier. The main being that you will save a lot of money by having such an appliance in your home. In the long run, many people recommend a filterless purifier due to their energy-efficient operation. So, if you choose the right model for your needs, you will not see a considerable difference in your electricity bill

To find out how to choose the right one for your particular home, take a look at some of the features that you should look for:

Cleaning – As many models have filters, you have to look at how easy they are to clean. Without such important areas being properly maintained, you cannot expect it to work at its full capacity. The sections can become clogged and eventually stop purifying the air.

It’s important to mention that even though some units use ionization as a form to purify the air, it doesn’t mean that they’re harmful to your health. Instead, you should clean them once a month as they will give untraceable amounts of ozone in the air.

Coverage Area – Whether the purifier has a filter or not, you should take a look at how much space it can cover. That particular number is a clear indication if it’s suitable for your particular needs. Some models mentioned can cover spaces up to 1,000 sq. ft. Thus, they can be used for large areas or commercial-needs.

If you have a small to moderate-sized home, you should consider a model that covers less than 500 sq. ft. to ensure that it can clean your home properly. If the purifier is too powerful for your home, it doesn’t mean that it’s necessarily better.

Noise Level – One of the best models are the ones that can produce minimal noise. The reason for this is because you want to ensure that you can use it without distracting others. Some of the units mentioned will barely produce noise or any at all. Therefore, you can place it in rooms such as bedrooms or nurseries.

On the other hand, if some produce more noise than 60 dB (A), it means that it works on their highest speed. Thus, the air will be purified faster. Whichever one you choose depends on your needs.

Dimensions – This is another feature that you should consider. For example, if you have a small area, you shouldn’t consider the bulky models as they will take up too much space. Measure the space you have to figure out which one is the best option for you.
