Top 10 Best Air Purifier for Small and Large Spaces

Over the time, pollution has now almost become an integral part of the life in urban settlements. No matter which metro city you refer to, you will come to the understanding that the residents all the metro cities struggle with pollution in one or the other way. Despite continuing efforts from the government as well as other private institutions to prevent pollution, there has not been any substantial positive difference in the poor quality of air. The air quality index of the major urban settlements is barely showing any improvements.

As a board-certified allergist, I’m often asked, “what air filter should I buy?”. First of all, do you need a filter at all? If you’re allergic to just dust mites, don’t bother. Dust mites are carried on large particles (10 micrometers, or microns), and only stay airborne for 15 minutes after being disturbed (such as making the bed or running a vacuum cleaner). They won’t even get to the filter, so no matter what filter you buy, it can’t filter something that doesn’t STAY airborne. But if you’re allergic to something carried on tiny (~ 2 micron) particles, such as cat dander or grass pollen, then by all means consider getting an Air Purifier.

Due to this degraded quality of air in the around us, we are exposed to a plethora of diseases. Many studies have shown that the poor air quality index and increased pollution in the cities is one of the major reasons why there is an alarming rise in the number of people suffering from respiratory diseases. These are the diseases which are spread due to pollution in the air along with bad air quality. Ranging from respiratory diseases suffered by adults to other health hazards which are faced by pregnant women, there are a zillion ways in which the bad air quality can have direct and negative impacts on the health of the people who are exposed to it.

Taking all this in consideration, we conclude that there is an existing dire need to install air purifiers in our homes, offices or other such indoor places to ensure that no one is no longer exposed to a zillion diseases of which they are not even aware. The air purifiers do this task of ensuring that people are not exposed to bad quality air by removing air contaminating elements from the air which is present indoors. Hence, this alarming rate at which pollution is increasing is the answer to the question of why air purifiers are needed at all.

Knowing that the need for air purifiers is on the rise now due to polluted air around us, we will analyze and make out that which are the best air purifiers that one can buy. We know that not everybody excels in making decisions regarding which electrical equipment is to be bought next and what model should one go for. It is understood that any individual might face a lot of difficulty in coming to a final conclusion as to which is the perfect and most suitable model of air purifier as per his requirements. Considering that almost everybody is running on a paucity of time to check out all the good air purifiers in the market and then decide, we’ve listed down the top 10 best Air Purifiers for allergies, smoke or pet odour which shall help you in coming to a conclusion. From these, you can opt the one model which you think is sufficing your needs.

Best Air Purifier for Small and Large Spaces

1. Rabbit Air MinusA2

Rabbit Air MinusA2

This one is undoubtedly the best air purifier because of the numerable features that this one piece of brilliance offers. It is no doubt that this Air Purifier which has sought number 1 place on our list of top 10 air purifiers is also rated to be the best Air Purifier product of 2018. 

This one has 3 features that were new to me. One was an adjustment to sense pollen in the air (plus another adjustment to make it more sensitive). Another was the automatic “Sleep” function: When it gets dark – and it got dark in my living room early last night – the “mood light” goes out and the fan slows down.  The third feature, one that I thought was frivolous and stupid, is that Mood Light. It is the band of light you see in the picture. It is solid blue if the Air Purifier is sensing dirty air. It changes color if it is sensing pollen. I have been a meditator for 40 years. I find this Mood Light to be calming and it helps me focus when beginning to meditate. So is by far the best best air purifier for allergies.


  • It is enabled with a technology of 6-stage air purifying technique which results in the cleanest and freshest air that is possible.
  • The front panel of this purifier can be adjusted in design as well as color by the user which is one of the most artistic features that is rarely found in purifiers.
  • Also, it has several kinds of filters such as the Pre-filter, Medium Filter, BioGS Filter, Carbon Filter & customized Filter which ensure the optimum performance of this best air purifier of 2018.
  • It has the capacity to serve an area of about 700 sq. ft.
  •  The Pre-filter prevents other filters from large particles to ensure the longevity of those filters.
  • This comes with a 5-year warranty for customer satisfaction.

The only demerit that you can stumble upon for this one is that the price might appear to be a little too high to you as compared to other options available in the market.
