Benefits Of Rainbow RainMate Air Purifier

There are no filters in this air purifier other than water, that make it unique as well as budget-friendly. Due to which no expense for replacing or cleaning filters like other air purifiers in the market.

If you google, the cost of these replacement filters, it’s huge. If you ask me, this purifier not only saves money but time too.

On the other hand, if you look at the normal air purifier in the market, you need to replace their filters in 3-6 months that can be a task on its own. However, in the Rainbow RainMate air purifier you just need to replace water when it gets dirty and you are done.

Rainbow RainMate Air Purifier Additional Features

This air purifier comes with a LED light to illuminate the water basin. It can be a good inclusion for any bedroom and a useful feature, you can use it as a nightlight when it gets darker. However, you have an option to switch it off anytime if you don’t need it.

Rainbow RainMate air purifier comes with two, dim, and high brightness settings. High brightness suites for the day time and low for the night.

How Good Rainbow RainMate Cleans Germs?

Honestly speaking, RainMate is great at capturing dust and freshening rooms but not as good or efficient as other air purifiers in the market. This purifier is not effective when it comes to removing super fine dust particles, smoke, or mold.

Therefore, if you need an air purifier for removing ultrafine particles and harmful pollutants or you need something that deals with allergies then this is not the product for you.

It’s a basic air purifier for normal dust, if you have more demanding surroundings then I would recommend you go for an air purifier that helps in eliminating allergies and fine particles.

air purifiers that come with a True HEPA filter can be a good option for you if you need something that removes dust particles as small as 0.3 microns such as allergies, mold, smoke, and irritants.

Don’t expect much from this air purifier other than dust removal & freshening scents otherwise, you’ll be dissatisfied. Rainbow RainMate air purifier suits for cleaning large dust particles from the air and add fresh fragrance.

Rainbow Air Purifier Set Up & Instructions

Thanks to the good build quality, you can use it as long as you need. Also, don’t worry if the water level goes low, it’ll automatically switch off itself. You need to refill the water once for a day.

Moreover, it can use for removing the cooking food smell of the kitchen and cigarette smell as well.

Final Thought On Rainbow RainMate Air Purifier

This air purifier is more suitable for removing dust and adding fragrance in the air, therefore, if you are looking for a machine that does that, you can buy this machine.

Moreover, this is not a machine to remove fine dust particles or eliminating allergies from the air, RainMate is a budget-friendly air purifier with no maintenance cost of replacing filters every 3-6 months makes it even more affordable, unlike other air purifiers.

As I mentioned before, if you’re buying this Rainbow air purifier, make sure you know that this air purifier is not capable of doing heavy lifting like removing fine particles like PM 2.5, allergies, smoke (it can remove the smell but not the bad effect of it) or other airborne particles.

If you look at the cost, this is a simple machine for basic use, don’t expect too much at this price. If it is what you are looking for then this is the value for money product.
