Sharp presently sells about nine air purifier models in India. Their air purifiers have superior technology and higher grade HEPA filter, making Sharp one of the best air purifier brands in India.
In this review, we cover five of their best-selling models, including the air purifier with mosquito catcher- the first of its kind pioneered by Sharp. We also discuss the pros, cons of their models in general and specifically delve in to performance and maintenance of each model too.
Best Aspects of Sharp Air Purifiers
Best in class HEPA filter
As we mentioned in our buyer’s guide, the most important factors that affect the efficiency of an air purifier is its filter quality and air change rate per hour.
Sharp claims that its air purifiers use the best-in-class HEPA filter which is the H14 grade. This HEPA filter has a filtration efficiency of 99.995% of all particles of size more than 0.3 micron.
Below, you can see the HEPA grade and filtration efficiency of each HEPA filter-
Use of Plasmacluster Technology
As we discussed in our buyer’s guide, most of air purifiers with ionizers emit ozone gas as a by-product. Ozone gas is a lung irritant that can trigger allergy even in non-allergy and non-asthmatic individuals. Taking this in to consideration, Sharp has introduced an ionization technology called Plasmacluster that doesn’t emit ozone as a by-product. Thus, Sharp’s ionization technology provides all benefits of an ionizer without any undesired side-effects. The Plasmacluster technology can be switched on and off as per you need at the press of a button.
Difference between Plasmacluster Technology and Usual Ionizers
Regular ionizers discharge negative ions in to the air that attaches with dust and other airborne particles, making them heavier to fall down on to the floor or stick to walls.
Plasmacluster technology on the other hand produces both positive and negative ions using the moisture in air. The ions attach to pollutants and breaks down their surface and removes protein from the microbe’s surfaces before combining and returning to air as water vapour. As per Sharp’s company website, the safety of Plasmaculture technology is certified by 28 global research organization.
Not So Good Aspects of Sharp Air Purifiers
We know we are stretching it a bit, but their products are priced higher than the other brands available in the market. Of course they have better features and higher performance, but going a little easier on the prices would definitely make them a much more preferred choice.
You may have read in a number of reviews that Sharp air purifiers bought online doesn’t have warranty. When I wanted to buy an air purifier, I personally contacted Sharp customer care and have been informed that except a model Vestige Sharp , all other Sharp air purifiers bought online comes with a valid 1 year warranty.
Now, let us take a look at each of the Sharp air purifier models.
Performance: Sharp FU A28E is the entry level air purifier from Sharp. Filtration system consists of-
A pre-filter which is basically a mesh that captures corse dust, pet danders and other larger particle matter.
The H14 grade HEPA filter that captures all microbes, bacteria, dust, pollen and other allergens larger than 0.3 micron to completely purify the air before it is blown back to the surroundings.
In addition to these filters, FUA28E also uses Plasmacluster technology to freshen up the air and kill microbes.
Note that this air purifier does NOT have activated carbon filter.
The CADR( clean air delivery rate) of FU A28E is 140 m3/hr. The manufacturers advice using it in rooms of size up to 160 sq. ft. However, if you want to maintain a minimum air change rating per hour (ACH) of 4, which is advisable for allergy, asthma patients as well as for homes in highly polluted cities, then you will have to use it in a room of size 140 sq. ft. or lesser.
Read our article on CADR & ACH rating to know its importance in an air purifier's performance.
Now, when we take a look at other features, there are a few aspects which seem a bit lacking. For example, it doesn’t have an auto-restart function. So, you will have to switch the air purifier back on after a power failure. The air purifier doesn’t have sensors for odour and dust too. Neither does it have a timer.
The HEPA filter of Sharp FU A28E air purifier has to be replaced every 1-2 year depending on the environmental conditions and usage. It costs about Rs. 3000 for replacing the HEPA filters. For replacing the filter, you will have to contact the customer care and schedule a technician’s visit.
Performance: Just like every other air purifiers from Sharp, FP- F40E-T 31 also uses three stage passive filtration and one stage active filtration system, which comprises of pre-filter to capture coarser dust and pet danders; activated carbon filter to capture chemical fumes, toxins and VOCs; HEPA filter to capture up to 99.95% of particulate matter larger than 0.3 micron which includes microbes, dust, pollen and allergens. The final plasmacluster technology kills microbes, infectious substances and overall freshens up the air.
Now, let us take a look at the air flow rate. This air purifier takes in air at an angle of 20 degree, making it easier to collect dusts at the lower levels in the room. It has a maximum CADR of 240 m3/hr. Though the manufacturers claim that it can be used for rooms up to the 320sq. ft. size, in order to maintain air change per hour rating of 4 ( which is optimal for allergy and asthma sufferers) the air purifier should be used in rooms of size less than 240 sq. ft.
It also has features like haze mode, sleep mode, timer( 2, 4, 8 hours), odour and PM 10 dust sensor. The haze mode is found to be especially useful for cities like Delhi that have a high level of car and industrial smoke.
Maintenance: The pre-filter of the air purifier can be removed and it has to be cleaned with a vacuum cleaner or a soft brush at regular intervals.
The filtration set comprising of activated carbon filter and HEPA filter has to be replaced every 12-18 months, depending on the usage and pollution level in your city. In order to extend its life, you can clean the HEPA filter with dry brush or dry cloth and keep the filters in the sunlight for sun sanitizing and removing mold and excess moisture. Never use wet cloth to clean the HEPA and AC filter.
The filter set consisting of HEPA filter and activated carbon filter costs about Rs. 5000/- and can be brought through Sharp’s authorized retailers or by contacting their customer care number.
Performance: As mentioned for the above model, Sharp FP G50E W also uses a combination of plasmaculture technology and filtration system that consists of pre-filter, activated carbon filter and HEPA filter to comprehensively filter all particulate matter above 0.3 micron including microbes, bacteria, virus, pollen, dust and other allergens.
Sharp claims that FP G50E-W air purifier has a CADR of 306 m3/hr, making it apt for rooms as large as 310 sq. ft. Thanks to the high CADR and best-in-class filtration system, this is one of the highly-recommended models for heavily polluted cities like Delhi, Gwalior etc.
The air purifier also has timer, sleep mode and haze mode, PM10 and odour sensor contributing to higher level of user-friendliness.
Maintenance: The pre-filter of the air purifier has to be cleaned with a vacuum cleaner on a regular basis. The HEPA filter can also be cleaned with a dry brush or cloth and sun sanitized every 1-2 month to kill microbes and eliminate any mold or odour. The filter has to be replaced every 12-18 months depending on the level of usage and pollution. It costs about Rs. 5000/- to replace the complete filter system through Sharp’s customer care.
Performance: Sharp FU-A80E uses similar filtration system as FP G50E-W. It consists of a pre-filter that is a standard mesh to capture pet danders and coarser dust particles that are visible to naked eye; activated carbon filter that captures odour and volatile organic compounds (VOC); HEPA filter that captures particulate matter like dust, allergens, pollens and microbes larger than 0.3 micron with 99.95% efficiency and finally, the plasma cluster technology discharges ions to kill microbes by attacking its proteins and thus overall freshens up the air.
This air purifier has one of the best-in-class CADR of 480 m3/hr. The manufacturers claim you can use it for rooms as large as 600 sq. ft. However, for better cleaning efficiency and maintaining an air change per hour rating of 4, it is advisable to use it for rooms of size 480 sq. ft or lesser. If you think about it, this is an air purifier that is suitable for large livings and bedrooms rooms in apartments and houses.
( ACH rating of 4 or above is recommended for homes in heavily polluted cities and for allergy and asthma sufferers.)
Other features of the air purifier include 20-degree angle in take to maximize air flow from lower levels, auto operations, ion shower operations (plasma cluster at press of button), PM 10 dust sensor and child lock.
Maintenance: The pre-filter of this air purifier is a standard mesh that can be cleaned with a vacuum cleaner at a regular interval. The HEPA filter has to be kept in the sunlight for sun sanitizing against microbes, bacteria, virus and for preventing mold formation. As for replacement, the set of activated carbon filter and HEPA filter comes at a cost of Rs. 9400 approx. and it has to be replaced every 12-18 months depending on level of usage and pollution in the environment.
Performance: Sharp FP-FM40E-B is supposed to be the world’s first air purifier with mosquito catcher. Let us take a look at the air purifying function and mosquito catcher function separately.
The air purifier uses multiple stage filtration that includes pre-filter, activated carbon filter and HEPA filter for cleaning microbes, dust and all other particle matter larger than 0.3 micron. It also uses plasma cluster technology to kill microbes and freshen the air. Basically, it is just like every other model we mentioned above.
Now, talking about the air flow, the air purifier has a CADR of 240 m3/hr, making it best suitable for areas lesser than 240 sq. ft. In larger areas, it won’t be able to attain the air change per hour rating of 4, which is ideal for homes in heavily polluted cities as well as for asthma and allergy sufferers.
Other features include auto restart function, dust sensor and air quality indicator.
As for the mosquito catcher, the dark coloured air purifier emits blue light which attracts the mosquitos. The powerful airflow of the air purifier sucks in the mosquitos and gets stuck on the strong glue sheet. The glue sheet has to be changed monthly. So, is it effective? There are a lot of positive reviews about it and a few negative reviews too. If mosquitoes are a real nuisance at your home and in plenty, then Sharp FP-FM40E-B will be a real relief. But if it is far and few, then, you may not really find it to be of much use to you.
Maintenance: The maintenance of pre-filter and the set of activated carbon filter + HEPA filter is just like every other Sharp air purifier. In addition, the mosquito glue sheet has to be replaced monthly and it costs approx. Rs. 1000/-
