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 is no filter media to replace.

Check out air purifiers with washable filters if you want to invest in a cost-effective system as these products, while they do indeed rely on filters in their operation, they do so without costly upkeep as their filter media is cleanable and reusable.

Allergy Triggers


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, 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.

To upkeep proper humidity levels, check out the best dehumidifiers that, through their operation, relieve the air of the excess moisture that enhances chances of dust mites lingering.

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.

Check out these air purifiers for dust to see what your best options are when it comes to ridding the air of this common pollutant.

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, the use of an air purifier is recommended as 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.

Mold grows sporadically where high humidity resides, so you should check out the best dehumidifiers for bedroom to make sure that the room you sleep in doesn’t harbor the health-threatening particles.

How Does a Filterless Air Purifier Work


The only considerable difference between filter and filter-free systems is that filter-free units are much less cheaper in the long run as there are no purification media to replace. As you may have noticed, 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 easier to maintain as all you need to do is clean them from time to time through vacuuming or wiping with a damp cloth, depending on the situation. When it comes to the types that you can opt between, 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. A great example is the LightAir IonFlow Evolution 50 that flaunts an energy-efficient operation as well.
  • 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 a number of 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 a number of 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 to run them day and night as the amount of noise produced is minimal. Generally employing a 3-stage purification process, these models can be able to collect allergens as small as 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.


Buying Guide


In the long run, many people recommend a filterless system due to the energy efficiency it flaunts, as well as the low upkeep costs. But exactly how do you know the choice you are making is suited for your needs? To learn what you should look into, follow the advice given here.

Coverage Area – Whether it 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 system you invest in is more powerful than needed, no actual difference will exist in performance, but you will end up spending more than you should on running it.

Noise Level – It is important for the system to be as silent as possible so that it won’t present a distraction no matter the room you utilize it in. This is a stat you must look into especially if you plan on using it in the bedroom or nursery.

Dimensions – 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 available to figure out which model is the best option for you.
