Without doubt, every sane person should consider his health to be a cornerstone of his life. Therefore, a clean air is important for our well-being. Luckily enough, mankind can enjoy many benefits of civilization nowadays. Modern air purifiers provide safe air for our homes and other premises. But some models of these devices can be rather unhandy due to cartridges requiring regular replacement. Fortunately, the manufacturers offer a unique solution solving the problem. A new no-filter technology will make your home atmosphere crystal clear, healthy. Moreover device maintenance will be easy and free.
Filterless Air Purifiers: Operation Principle
Modern systems of no filter air purification can surprise every buyer with their work. As the name implies, such purifiers do not have a filter. The secret of the device effectiveness lies in the presence of physics, which provides electrostatic charging on the back side of a purifier. Due to the collector’s metal surface the particles of dust and other contaminants are attracted like a magnet. Thus, such a device doesn’t require any mechanical filters and is unique among suction principle systems.
Such type of air purification system is also called ozone, ionic or electrostatic. Unfortunately, these devices can have some drawbacks. Some filterless air purifiers can be less effective than those with cartridges. In addition, the metal plate cleaning is sometimes more complicated than a filter replacement.
But the most important argument against these devices is ozone – a gas releasing while the purifier is working. Luckily, if you choose a reliable trade mark such as Airocide, AirFree, Envion, Light Air or RX Air Plus, your health will be completely out of danger. Furthermore their air purifiers are very effective, noiseless, compact, safe and have affordable price.
No Filter Air Purification System Types
Filtered air purifiers are not very convenient: they are bulky, noisy and require careful monitoring and replacement of expensive cartridges. Fortunately innovation technologies grow extremely fast.
Air purifiers without filter is a great alternative for your home. There are three kinds of no filter technology: electrostatic, UV and ozone.
Electrostatic air purification systems
Such appliances are highly effective and remove contaminations due to an electrostatic charge. The dust is accumulated on charged metal plates containing wires.
This type of air cleaner apply UV light to kill bacteria and mold. Ultraviolet models are the most energy efficient devices in comparison to other purifiers.
This unit removes impurities due to ozone or some oxidizers. Such system also destroys 99,9% of pathogens. Ozone purifiers are safe, handy and power efficient.
The Difference Between Filter and Filterless Air Purification Systems
The market of air cleaning equipment presents a variety of air purification systems. The majority of them are filtered.
Technology with filter provides air suction by the fan. The inside filter removes dust particles and then clean air leaves the device. Naturally, such system requires regular filter replacement. Most manufacturers recommend changing cartridges every six months.
A filterless system uses the technologies which are discussed above. You should pay attention to the most popular brands and watch through filterless air purification reviews on the special customer forums like allbestairpurifiers.reviews.

Reasons to Make a Purchase
Every customer faces a great diversity of air purification systems. Filterless or filtered – you might be wondering at this issue. The recommendations below will help you make the right choice.
No additional investments
If you go for a filtered air purifier additional costs will apply. For example, a filter replacement should be held twice a year, as most manufacturers recommend. While filterless models do not require any additional investments. If you wish to save your budget, choose no filter technology.
More effective at destroying bacteria
Filterless purifiers for air are definitely more effective at destroying pathogens due to negative ions release. Their filtered counterparts remove dust, but are not so effective at killing viruses like flu, strep or staph.
Eliminating airborne impurities with high efficiency
The main factor when choosing filterless air purifier is its efficiency. Other technologies can boast this capability too, but only ionic devices make this solution ideal. The matter is that ion molecules attach even to the smallest particles making them bigger so even the microscopic impurities are caught and removed from the air.
The benefits of filterless purification technology are obvious:
- Lower price in comparison to filtered purifiers;
- Efficient technological innovation for attracting contamination;
- No hassle of regular changing filters.
In this review we have also found out all necessary characteristics of the device in order to help you to make a right choice.
This tech characteristic should be a bit greater than the space where you are going to use the purifier. For example, if your room is 100 square feet, you should consult an Instruction Manual of the chosen air purifier to be sure it is able to cover at least 105-110 square feet. In this case your air will be definitely clean.
Level of removed airborne particles
Keep an eye on those models which are capable to eliminate 99% or airborne particles.
This aspect is sufficient if you don’t want to spend much money on your energy bills. Remember, Energy Star certificates are given to the most power efficient models only. So, look for it while choosing your air cleaner.
Wherever you are going to place the device – nursery, bedroom, kitchen or other rooms, you must make sure that a purifier you invest is silent. Otherwise, the noise will bother you when you sleep or work.
It is not so necessary as other aspects, but some customers prefer units with backlights, or LCD screens, or casters to move the device from one room to another with no effort.
Make sure the manufacturer covers a purification system for a generous amount of time (at least 1 year). If something happens to your unit, you will not spend money for repairs.
