An air ionizer will be a perfect decision for those who suffer from allergies and people thinking about effective air purifying in their apartments.

Pointing out the positive aspects for air purifiers won’t help you make the best decision. So, we shared not only features and advantages, but also the disadvantages of best air ionizers in 2018 that you may want to consider.

Air ionizers are devices that generate negative ions and add electrical charges to the air molecules in a room. These ionizers purify the air in your home by attracting and capturing bacteria and other particles in the atmosphere such as dust, pollen, mold spores, and other non-hygienic, unpleasant particles, causing them to stick to the floor or other surfaces where they can be vacuumed up and removed. You’ll be shocked at how much easier it is to breathe with one of these things in your house they also help neutralize odors to boot.

How does an Air Ionizer Work?

Let’s briefly go through the functioning of an air ionizer.

When a necessary voltage is applied to a series of inbuilt needles, the ionizer discharges a stream of electrons into the air. These electrons attach to the air molecules forming negatively-charged ions. The negative ions then attract positively-charged dust particles, dander, allergens, etc. in the air forming a cluster. The cluster then becomes heavier and either fall to the surface or is easily sucked into the air ionizer and gets collected in the filter. The filters can be cleaned or replaced when needed.

5 Things to Remember Before Buying an Air Ionizer

With no industry standards in place in India, consumers are at the mercy of the brands. Prices of air ionizers can range from anywhere between Rs 8,000 and Rs 1 lakh. There are many factors to consider before buying an air ionizer.

It is very important to go through the specifications of each model and not blindly believe the sales executive. This buying guide aims to help you take the best decision.

1.Particle Removing Capability

Particle removing capability vary in the different type of air ionizers. Some air ionizers are more effective than others in trapping the different sizes of airborne particles. Air ionizers with HEPA filters are good at collecting allergens and other fine particles.

2. Removal of Chemicals & Smoke

Not all air ionizer brands are good in getting rid of cigarette smoke, chemicals, and unpleasant odors. It will be better to check for activated carbon air ionizers to tackle with the smoke and odor problem.3. Coverage

It’s important to check the area that an air ionizer can cover. A standard ionizer can effectively cover an area up to 300 square feet. There are different models that can cover greater areas. Before buying an air ionizer you will have to measure the square footage of your room. Depending upon the area needed to be covered, you can either choose a unit that can be placed on the floor or be mounted on a shelf, wall or a counter.

3.Price and Maintenance Expenses

The price of an air ionizer is an important factor to consider. You may want to choose an affordable as well as an effective model at the same time. The replacement cost of filters is also another determining factor. By knowing what the replacement is, you can figure out the total lifetime cost for the unit.

4.Energy Consumption

Some units consume more power than the others depending on the air ionizer technology. Before choosing a model, check for its power consumption.  Standard power-saving air ionizers use about 40 watts of power.

5. Noise

Most air ionizers run smoothly in the room without disturbing the quietness of the surroundings. However, some high power units make noise while drawing greater volumes of air. Check for the amount of noise produced before selecting the ionizer so that you do not spoil the peace of your home.

Do you have seasonal or year-round allergies and looking for a solid way to get relief?

Are you tired of relying on costly medicine to get you throughout the allergy season?

If so, then you’re not alone.

We know that pollution rates are increasing day by day.  Air purifiers have emerged as one of the saviors to fight the increasing complications due to air pollution. Every year, the risk of rising in health-related issues increases, especially in the major cities. While outdoor air pollution leads to serious health problems, indoor pollution is much more harmful than that. According to WHO, about 4.3 million people die from being exposed to household air pollution.

To control this, several companies have devised air purifiers which can improve indoor air quality. It is believed that within the span of 2 hours, these air purifiers can improve the air quality from hazardous to good. Seeing the rise in demand, most of the big brands have started making air purifiers of different specifications and price range.  But, before you make a purchase, it’s necessary to look at some important factors like room size, filter replacement charges, standard certification, noise levels, electricity consumption, etc.

When you are about to buy an air purifier, make sure it uses a HEPA (high-efficiency particulate air) filter. This type of filter qualifies certain standards set by the United States Department of Energy.  The ability to remove 99.97% of tiny (0.3 micrometers or bigger) airborne particles.  Doctors say this type of filter is extremely effective at removing any airborne allergens. They are recommended to keep on at all times in order to reach its full air-cleaning potential. Also make sure to replace the filter as often as the manufacturer suggests, usually every six months to two years.

So, in this piece, we have listed some of the best air purifiers which you can use to stay void of such vulnerabilities.

Things to Consider While Buying an Air Purifier

  1. What do you need?

When choosing an air purifier, first of all, consider your indoor air quality needs. Like, if you have allergies, you should choose air filters specially designed for allergy relief.  Air purifier models called HEPA filters or High-Efficiency Particulate Air filters which are proven to eliminate 99.97 % common airborne allergens which are sized at 0.3 microns and larger.


  1. Filter Efficiency

The efficiency of an air purifier is measured by the particle size being captured. 0.3 microns or smaller is an excellent capture size for an air purifier. Pollen, mold, pet dander, dust, and bacteria are sized in between 0.3 to 5 microns. A HEPA filter can easily trap these contaminants or anything bigger than 0.3 microns.

Contaminants like viruses, chemical fumes, and cigarette smoke are smaller than 0.3 microns and cannot be filtered out by HEPA filters.

If you are looking for an air filter to remove these contaminants you will need to purchase an ionizer, activated carbon filter, or an Ultraviolet air purifier.


  1.  What features do u need?

After choosing the type of air purifier you need, consider whether or not you need any special features.  Additional features can include caster wheels, handles for easy mobility, digital controls, remote controls, multiple fan speeds, filter change indicators, programmable timers, air quality sensors, etc.. These additional features can add convenience to the operation and give you greater as well as easier control over your air purifier’s performance.


  1.  Noise Level

Operating noise can become a concern when the system is running throughout the whole day.  Most air purification manufacturers list a decibel rating for each of their air purifiers fan speed. The chart below gives you an idea for the level of sound an air purifier will make based on its decibel measurement.

10 dB – Breathing

20 dB – Falling Leaves

30 dB – Whisper

40 dB – Raindrops

50 dB – Average Home

60 dB – Normal Conversation

70 dB – Vacuum Cleaner


  1.  Clean Air Delivery rate

Clean Air Delivery Rate (CADR) is a standard measurement of the total volume of air that an air purification system can purify from a specific pollutant in one hour. A higher number CADR indicates the unit is more efficient in cleaning the air of that particular pollutant. Another measurement to note is the Cubic feet per minute (CFM). This is the amount of air that flows through the purifier in a minute. This is important because you will not receive the full benefit from your air purifier if the amount of air filtered per minute is very small. For reference, 350-400 CPM is a more powerful air purifier.


The Top 5 Air Purifiers for Allergies

Now you know what to look for in an air purifier, we’ll list below the top five air purifiers specially designed for allergy issues. These devices continue to top the charts with customer reviews and include the most important features necessary to help with allergy symptoms.

#1 Mi Air Purifier 2S (White)

Mi Air Purifier 2S comes with an ultra clear OLED display and the Mi Home App can be used to remotely control your purifier from anywhere, set auto on and know the air quality and filter status. The display also shows temperature and humidity levels.

The Purifier is meticulously designed to reduce noise while it cleans your air. In sleep mode, the sound produced is very low, so that your sleep is not disturbed. Its display brightness is also adjusted with ambient light.

#2 Blueair Classic 280i

Meant for room sizes of 280 sq. ft., the unique feature purifier is the presence of an air quality sensor that speeds up the fans automatically whenever it detects a drop in the air quality of the room. Apart from that, the Classic 280i purifies the air using their patented HEPA Silent technology. It has a smart panel on top which displays the Wi-Fi connectivity, fan speed status, filter status and the air quality of the room and VOC levels. The Blueair Friend app will let you control all the modes remotely without touching the purifier. You can also monitor the air quality of your room in real-time and accordingly set the fan speed.


The Blueair Classic 280i is slim, lightweight and easy to move around your home

LED icons

In addition,  it features the easy-to-read LED icons to let you see the status of your air purifier’s Wi-Fi connection, operating speed and filter status.

#3 Vax Pure Air 300 Air Purifier

The cylindrical Air Purifier is attractive in glossy white plastic and is easy enough to be placed. It has a HEPA filter – designed which lasts three to six months, depending on usage – and an ionization option. The purifier’s front panel is dominated by simple touch controls that let you power on the purifier, control the fan speed, use the timer, and toggle the ionizer function. These options are also available on the slim-line remote control.

The big indicator light on the front changes color to display the current air quality, moving from green through amber to red. At minimum fan speed, I found the purifier ran at 35.9dB and a more intrusive 62.1dB at max. The night mode cuts the status lights and drops fan speed to a lower level, with the sound falling to a quiet 33.4dB. Although it was still audible, you could easily sleep through its low-level noise. Power efficiency is excellent, with max power drawing a peak of 53.8W, and the minimum setting just 7.2W

Most people will find it easiest to run the Purifier in automatic mode, with the device choosing the best fan speed to deal with current air conditions. Still, there’s a timer option – hourly increments between one and eight hours – if you want the purifier to power down.

Regarding effectiveness, the purifier has high CADR ratings.If you want a powerful all-rounder, this is the model to buy, and it’s suitable for rooms of up to 120m2.

#4 Philips Air Purifier Anti-Allergen

Most of the air purifiers are rather drab-looking, but Philips has gone all-out with its Air Purifier Anti-Allergen with NanoProtect Filter AC3256/30. It looks great. Tall yet relatively thin, this air purifier is easy to tuck out of the way. It has a particulate matter (PM) sensor.

This model comes with two filters. There’s a NanoProtect filter that reduces odors and can filter some VOCs; it lasts for up to 12 months. Then there’s the HEPA filter, which lasts for around 24 months. Thankfully, the purifier notifies when both filters need replacing; if you don’t do the job within 14 days, the entire machine locks down to avoid damage.

All controls are accessed from the top, using the touch-sensitive panel. Unfortunately, there’s no remote control. Parents will be pleased to discover that there’s a child lock, stopping little hands from activating the device. From the control panel, you can choose the fan speed, set the timer (in one-hour increments between one and 24 hours), and adjust the brightness of the controls.

If you want a super-quiet air purifier or a model that’s designed for pollen and allergies, then this is the model to buy. It’s suitable for room sizes up to 95m2. The Vax Pure Air 300 is slightly cheaper and a better all-rounder, but it doesn’t look quite as nice and it’s louder too.

High CADR ratings in all categories show that this is a powerful air purifier, slightly behind the Vax Pure Air 300.

easy to use controls

Most people will find it easiest to operate the purifier in automatic mode, where the fan speed ramps up as the air quality deteriorates. There’s a standard Auto mode and a more sensitive Allergen mode. Usefully, the color lamp at the front offers a visual indicator of air quality, moving from blue (good) through amber to red (poor). This lamp is dimmed when you dim the controls. At the lowest setting, the purifier is silent. At full tilt, sound jumped to 56.7dB.

Wattage: 60 Watts

Item weight: 9.8 Kg


#5 Dimplex DXAPV3N Air Purifier

This purifier is a small box that’s designed to fit on a desk. It’s also one of the least expensive HEPA-filter purifiers available. It can’t display the current air quality; there’s no remote control, and there’s no sleep timer. There’s a carbon filter built in, designed to neutralize odors, and it emits negative ions to help reduce the risk of some viruses.

The operation of the purifier is simple, using the two-speed dial on the side. At the maximum setting measured noise at 49dB; switching to the low-power setting, the sound dropped to 47.4dB – which is still fairly loud. It’s a shame that there isn’t a quieter night-time mode. Power efficiency is pretty good, with the purifier drawing 24.8W at maximum power, dropping to 15.5W at a minimum.

At maximum setting, the particulate matter from our insecticide spray took just under five minutes to return to normal levels. That’s comparatively slow and confirms that this really is a product for a smaller room. The official CADR ratings bear this out, with low ratings for smoke, pollen, and dust: There’s no warning to tell you when the filter needs replacing, so regular manual checks will need to be made.

If you have a small office or bedroom, the Dimplex DXAPV3N Air Purifier could be a good choice.

What else should I look for?

Finally, when you are about to choose your purifier you can look out for the Clean Air Delivery Rate (CADR), which tells you how effective the purifier is at different types of allergen, compared to introducing clean air. For example, an air purifier with a CADR score of 190 for dust particles is as effective as adding 190 cubic feet of clean air per minute. In short, the higher the CADR rating for each type, the better. And, CADR scores are comparable across all products, helping you make the right choice.
