    A tiny miracle!! Considering the herd of air purifiers available in this price range this offers wonderful value for money packed with performance and a look that is understated. The airflow is terrific and the company says the technology is globally certified. That's safe.

  • Great for their plasmacluster tech, BAD for passive filtration!
    Rahul on Amazon.in | 01-01-1970

    First, the bad part. To start with, don't be misled by the description of this product, this model DOES NOT have a HEPA filter at all! ...instead has an E10 grade 'dust filter', which does not qualify for being a HEPA. Sharp clearly states this in their footnotes on the product description page, for this model, on their Singapore website. "E10 class in EN1822 not conforming to the HEPA definition based on the JEM 1467 standard" Notice the words "NOT CONFORMING"? It doesn't end here though, Sharp India goes about bragging on their website, as well as on a number of other places including Amazon's product description for some of Sharp's other air purifiers and also on Sharp India's YouTube channel... "All Sharp Air Purifiers sold in India are equipped with highest class H14 HEPA in EN1822 type" Which is how I, and perhaps many others got tricked into buying this model! What's the big deal about filter grades you ask? E10 filters do not have an efficacy exceeding 85% filtration of 0.3 micron particles, while H14 HEPAs can filter out 99.975% of the finest particles down to 0.3 microns. Which means the E10 leaves nearly 15x more pollution than a HEPA filter! HEPAs also do a terrific job of filtering out most bacteria and many viruses too though not all. Yes, surprisingly HEPAs work even better for particles the size of 0.01 microns many viruses fall in this size range, though bacteria are far bigger and easier to trap than 0.3 microns i.e. they follow a parabolic curve in terms of particle filtration, counterintuitive but True. While the E10 will simply throw them right back into the air! H14 HEPAs also last Significantly longer than other grades. Which is why NO hospital or even a general business enterprise worth their salt would ever use an E10 filter in their air purifiers of choice. The manual too DOES NOT mention the word HEPA anywhere, while clearly calling it a "dust collection filter" I probed further and figured that HEPA filters have several pleats, are dense and rather stiff. I then compared it against the HEPA in my Kent vaccum cleaner and the Sharp does not have half as many pleats, is NOT dense and has a flimsy appearance. The vaccum cleaner itself does not seem to use a True HEPA, but... It's definitely better built and denser than Sharp's E10 'dust filter'. Pros 1. Plasmacluster tech is validated to work - kills many kinds of pathogens down to 0.01 micron, removes static, neutralizes many odours and VOCs, and works 'actively' i.e. works against anything that it comes in contact with, with the air it travels along. Sharp has a lot of video demos check YouTube and certifications to support their claim. They've also made objective side-by-side comparisons with other brands. I am a believer! 2. CADR is good enough for a room of size 12x12x10ft. Their CADR itself is compromised though, as explained earlier 3. I could feel a sense of freshness in the room 12x12x10ft. after 2hrs of running in a moderately sealed room doors and windows closed. This does not necessarily mean it's doing a GREAT job, but only indicates that it has improved things, which is a no brainer - some filtration is better than none. 4. It's Very quiet! even on the highest setting which is what you should always be using, given how weak the filter is you'll need endless cycles - the pathogens though will only find them to be joyrides 5. Great price - ₹4.6k. If you buy it for the plasmacluster tech alone or if you are happy to replace their filter with a third party's True HEPA Google - smartair filters Cons 1. As mentioned in the litany above, it does not have a HEPA so the passive filtration is a bad joke! As the filter is designed to simply throw the bacteria & viruses back into the air, along with many of the other finer dust particles that we DON'T need to inhale. Which is why we buy an air purifier, Sharp! 2. The CADR to Watt ratio is a poor too! 168 m3hr on consuming 48w. A ratio of just 3.5x?! compare that to Blueair's Joy - a CADR of 200 m3hr on consuming just 10w. A ratio of 20x! Or to put it differently, the Blueair is nearly 6 times more efficient than the Sharp! And that much more pocket friendly to run 24x7... And has a HEPA too, one that's electrostatic it charges particles on the 1st pass which are then caught in the subsequent pass 3. Their senseless E10 filter costs ₹2.2k to replace if you insist on making that mistake, after making the mistake of buying this model! ...or you can get a True HEPA at nearly ₹1,000 lower! 4. No fine dust filter, No carbon filter. Even if you do plan on adding those the CADR would probably fall by 50%, making it fit for nothing more than a small bathroom. Not to mention, you'll strain the motor, up the noise and significantly reduce its life. 5. Lights can't be turned off. The one up front is especially big, bright and bothersome. Like me, you may have trouble sleeping with this one. I can list at least 3 more meaningful Cons, though that'll simply be too harsh for the asking price - just ₹4.6k! post discounts In conclusion... This is NOT a HEPA-based air purifier, so You should either... 1. Solely buy it because you believe in the 'Plasmacluster' promise which is validated and makes sense by itself. That would also mean you have another dedicated 'True' HEPA based air purifier for passive filtration. Why would you then not instead buy the next model from Sharp themselves?! 2. or Add an H12 HEPA still a 'True' HEPA from Smartair. It fits, and costs a mere ₹1,300 3. or simply buy the next model from Sharp; FP-FM40E-B ₹14k or so an Amazon exclusive. Comes with all the bells & whistles and I cross-checked for its specifications consistency across geographies and marketing material - All OK on this one. Beyond a point, I'll take Sharp's word. They are Japanese, make Great products, with tons of investments in research, create mind-blowing tech like Plasmacluster... Though that's only valid until they aren't contradicting themselves!

  • Nice and cost efficient product from Sharp
    Anuj Aggarwal on Amazon.in | 01-01-1970

    Nice product

  • Does not provide information on air quality. Also output seems to be less
    tarun kandwal on Amazon.in | 01-01-1970

    It us difficult to say whether this air purifier works or not as there are no indicators on it to give air quality. There is no auto function so you have to manually adjust the fan speed. Air flow is adequate just for a single room. Though it may be doing its job but it does not say so!!
