Then comes a normal ionizer which works by improving the efficacy of the air filtration system. The ionizer can be turned on/ off. When this feature is turned on, the allergens can be trapped more easily be by the 75i’s True HEPA filter.

Alen’s True HEPA- B7 Fresh filter contains an activated carbon layer and can easily remove airborne allergens, pollen, animal dander, smoke from cigarettes, or cooking, wildfire, and household chemical & aerosol sprays fumes and thus helping in the prevention of many respiratory issues.

By adding an antimicrobial compound to the True HEPA (H13) filter, Alen has protected the filter from any bacterial and microbial growth.

9. Ivation Air Purifier

View on Amazon

Enjoy the sheer sensation of being alive while surrounded by that indescribable “clean-smelling” atmosphere that can only be found in nature.

This purifier is a bit different than others as it releases powerful negative Ions to purify and freshen up the area controlling maximum dust particles, allergens, and cleaning the air to help breathe you better.

Simply turn on the ionizer to experience substantially clean air quality as negative ions latch onto and remove the hazardous airborne particles from the air. It also generates beneficial ozone, pumping healthy activated oxygen into the space removing foul smells from tobacco, chemicals, pets, molds, and more.

Comes in an attractive cherry color wood exterior and stainless steel cabinet style that will last for years. A small but mighty device that will perfectly complement your home, office, or apartment decor.

Unlike a conventional filter, Ivations’s 2-in-1 ionizer and odor remover create numerous air effects making an exceptionally breathable room. The new 300B model by Ivation uses less power, has a quieter fan, better ion quality, and higher output than their competition.

There are two distinct, adjustable knobs on the left and right sides of the purifier. The knob on the left side of the control panel helps adjust the fan speed for ozone production, while the one on the right helps control the negative ion generator. Both these functions are independent of each other and are controlled separately.

The air ionizer feature emits negative ions that purify the air by removing even the tiniest hazardous particles. It covers up a large area of up to 3500 square feet, however, the most noticeable effect will be in the room where it is placed.

So this is an ozone generator, so I’d suggest using it in areas that aren’t frequently used, ensuring all the living organisms are out of the vicinity of the room when it’s switched on. Always remember when it comes to ozone, the Environmental Protection Agency has established the phrase “good up high, but bad nearby.”

The Expert Opinion
A highly recommended model, especially if you want to get rid of strong odors/smells, mold, or mildew. The additional negative ion generator function, on the other hand, gives this ozone generator even more versatility, allowing it to remove pollutants other than smells, molds, or mildew from the air. Breath it to believe it!!

Things Considers When Buying a Kitchen Air Purifier 

Although air purifiers are relatively simple machines, there might be some key parameters and functionalities left out if you don’t do your homework properly.

In the following section, we give you a walk-through guide to some key features which will enable you to make an informed choice when purchasing an air purifier.

Machine Capacity

The first & foremost thing is the capacity to clean air in specified room size. This factor is directly related to the size of your room.

You have to choose the capacity of the air purifier depending on the room size in which it would be used & it is always better to be on the larger side just to cover for the non-ideal environment like damped walls etc.

CADR rating

CADR is short for Clean Air Delivery Rates which is a measure developed by the Association of Home Appliance Manufacturers (AHAM) to help standardize the filtration of a specific type of pollutant particles in set room size.

As a rule of thumb, a higher CADR number means that the air purifier can remove more particles and vice versa. Some air purifiers have a single CADR number showing they are designed for only a specific type of pollutant; while other models may have filters for many different pollutants.

It is worth mentioning that some manufacturers follow the IQAirHealthPro standards instead of CADR rating; however such models remain lower in numbers.

Room Size

CADR rating associated with recommended area/room size is also an important feature that directly relates to your requirements.

For an average room size of 300 square feet, the minimum CADR number should be around 200 (cubic feet per minute), and similarly, for a larger 500 square feet room, you should get an air purifier with at least 350 cubic feet per minutes.

Types of Pollutants

Although there are all-in-one type air purifiers available in the market for your general air quality improvement; most machines are designed for anyone or two specific types of pollutants. Therefore depending on the environment, you can choose either for smokes or pets or kitchen smells.

Filter System & Types

Most air purifiers use two-layered mechanical filtration systems to physically trap the particles within them. The first layer is called pre-filter which stops the larger particles & pet hair etc. while the second layer is the main working horse which removes the different types of smells and odor from the air.

Pre-filters are just like those filters inside vacuum cleaners which may either be washable or disposable. The main filters are usually high-efficiency particulate air (HEPA) filters which can trap particles up to 0.3 microns small.

It is advisable to beware of the so-called “HEPA-type” filters which are claimed to be as efficient as HEPA filters but their working cannot be confirmed on the individual level.

These HEPA filters are often complimented with additional (activated) charcoal filters which specialize in removing Volatile Organic Compounds (VOC’s) often generated from cooking in the kitchen. Some air purifiers even have an extra layer of UV light to effectively disinfect the air from germs.

Filtration Maintenance Cost

In addition to the up-front capital required for air purifiers, you also need to periodically invest in the replacement of your exhausted filters for which some models have an indicator light.

You need to replace both layers (pre-filters as well as HEPA filters) once they have been used to their life which varies from filter to filter. Generally, expensive filters have longer operation life than the cheaper ones. Similarly, activated charcoal is also needed to be re-generated after certain usage cycles.

Noise Level

Generally, air purifiers are low-noise appliances with only a fan making a slight humming sound. Therefore these are very suited to be used in bedrooms especially for kids. Larger air purifiers however have somewhat higher noise levels sometimes going as high as 60 dBA.


Portability is another desirable feature that adds the icing to the cake. Most of the common sized air purifiers are equipped with a wheeled base with the exception of very large ones & depending on your use; you can opt for this feature without compromising the main things described above.

Energy Consumption

Typically, air purifiers consume very little electrical power depending on their fan size. On average, you can find an air purifier with a 50-watt power rating & it can go as high as 200 watts.

Some manufacturers have added an “eco” mode wherein they have particle sensors inside the air purifiers which put it on standby after reaching a certain purity level. Such models generally also have their Energy Star rating on them.

Additional features

There are also some additional features available on different models. Although these are not a deal-breaker, their presence on your appliance makes your life a lot easier. These include remote controller, Microprocessor-based control, integrated with smartphone apps, etc.

What are the Benefits of removing  cooking odor/smell ?

Getting a purifier for your kitchen is an intelligent decision, mostly because of the health benefits it offers, besides keeping your kitchen free of any cooking odors that tend to hang on, leaving your kitchen feeling fresh.

Different varieties and types of air purifiers are available on the market, each of which uses precise functions and machinery to undertake its filtration course.
