Xiaomi faces copycat charge from Japanese company over new air purifier

After taking heat for allegedly lifting design ideas from Apple, Chinese smartphone maker Xiaomi is now facing copycat claims over its air purifier device, which a Japanese company claims closely resembles its own product.

Xiaomi on Tuesday unveiled its smartphone-controlled “Mi Air Purifier” for the Chinese market. But local press in the country was quick to point out to similarities between Xiaomi’s product and an air purifier from Japan’s Balmuda, a maker of electric fans. Both devices are shaped similarly, and appear as tall rectangular boxes that can filter the surrounding air.

Late on Wednesday, Balmuda responded to Xiaomi’s air purifier, posting to its official account on Chinese social networking site Sina Weibo.

“It was discovered that Xiaomi’s air purifier is surprisingly similar to a product that we released in 2012,” wrote Balmuda’s head of product design Gen Terao.”I personally was very bewildered by this.”

Balmuda’s “Air Engine” purifier is also being sold in China, where it has been popularly received, the company said in a separate posting. Xiaomi, at one point, had even talked about a partnership, but Balmuda declined because its developers were too busy, it added.

In addition, Balmuda was also granted patents in both China and Japan that relate to the air purifier’s technology and design. Neither Xiaomi nor its affiliates have been granted access to these patents, Balmuda added.

“Balmuda is currently in talks with company lawyers to confirm whether Xiaomi made any infringements,” it said. “This will let us decide whether to take the next step in legal measures.”

Xiaomi’s own air purifier was developed in partnership with a local company it invested in called Zhimi Technology. On Thursday, Zhimi responded by stating that its air purifier was completely different from Balmuda’s in terms of technology and exterior design.

In an Internet posting, Zhimi highlighted the differences between the two products in pictures posted side-by-side. To develop the air purifier, the Chinese firm said it applied for 31 different technology patents relating to the fan and other key components.

Products including refrigerators, televisions, air conditioners all use a similar exterior look that’s based on mature design concepts, the company said. “We disagree with arguments that say ‘we must be different for the sake of being different,’ or that ‘we need to reinvent the wheel.’” it added.

The Xiaomi air purifier will be sold later this month at 899 yuan (US$146), while Balmuda’s product goes for 5499 yuan on Amazon.

Some of Xiaomi’s other products, including its smartphones and tablets, have drawn comments about looking too similar to Apple devices. In late October, Xiaomi vice president Hugo Barra defended the company from the copycat claims.

“Our designers, our engineers, are inspired by great products and by great design out there. And frankly who in today’s world isn’t?” he said.

Sharp brochure states "No (Deodourising Pre-Filter)" while FP-E50E states "Yes". Not sure what they mean by Deodourising Pre-Filter, but No prefilter. :s22:

FP-E50E looks a lot like China's FU-CD20. They have so many more models!

I'm now contemplating between these two models and the Samsung AX40 that you recommend. hmmm...

Once again, many thanks! :)

No worries, 98% of the air purifiers out there have prefilters, as in the aircon netting type. That's good enough "protection" against coarse Particulate Matter for a good 9-12mths usage with the main HEPA filter.

Xiaomi 75W - 406m3/h

Samsung AX40 34W - 323m3/h.

Doesn't seem to be very efficient to me.

It has a centrifugal fan to suck the air from the HEPA, and then this air is blown to a chamber before being sucked by another fan to to be blown out. That's why.


They said it has a small footprint. 26cm x 26cm = 636cm2

Samsung AX40 has 738 cm2. Not that much bigger actually. Samsung is 49cm tall.
Xiaomi is 73.5cm tall.

The Xiaomi they said is very noisy. Samsung AX40, no need to into much, it's the quiet king.

Samsung AX40 = SGD269 shipping inclusive from South Korea.

Lowest price in all of history. Have never seen it lower.

Good time to stock up if you wanna add more rooms for haze protection. Buy it and be protected for a few years at least. (these things don't break down if you get the correct workhorses)

Replacement filter, get from taobao. RMB110 for a customised 310mm x 282mm x 44mm H12. 44mm = damn thick, that's 1.75" thick.

Qoo10 - [SUPER TIMESALE]

Happy with the purchase 0 0 wen******* Jan 02, 2015 16:31:53 [option ] : Model:NEW AX40H5000GMD - 41.6㎡ (03.2014) / Filter:none Very fast delivery. Ordered on 28 Dec, received on 2 Jan. Item is in good working condition. The only problem is all instructions in korean language.

Whatever floats your boat bro. For me, I'd trust anything. The heart of the air purifier is the HEPA filter, followed by activated charcoal mainly.....but tests have found that in homes (other than just renovated ones or you have a big piece of new furniture made up of suspect glue) the TVOC and formaldehyde levels are extreme low.

The Samsung AX40, even in 220V 60Hz guise (SG is 240V 50Hz) has proven itself in reliability already. Got a couple of units operated in long operations daily for nearly 1 year liao. Winix, there were a few users who bought in 2013 via Amazon, but they did not report in this 2014 thread.

I bought the laser particle counter (98% sensitive at 0.5% but only 50% at 0.3 microns), should be arriving in a few day's time. It's to test the tiong HEPA filters myself, though they have already been tested and posted on youtube and youku.

Seriously very easy to get people to spend money nowadays LOL.


My recommended stuff are not 2k IQAir, but $100-200 + $15 replacement filter fare. The folks in this thread can afford that or even multiple units, they and do care. IIRC, you even do not have kids yet.

The other haze threads created by others you wanna play and have been disturbing multiple times since day 1, can...coz not my threads. But don't disturb this proper technical and lobang sharing thread, can? You are just making yourself look bad in this thread in front of all those who have chronic medical conditions (quite a few here and in other threads), parents and pregnant mothers.

Guys

Where to buy Samsung AX40 filter ?

Qoo10 cheapest is 82$

worth it ?

Alternative is aliwangwang (taobao's IM platform) this seller. He can customise H12 grade HEPA for you. Just plain HEPA will do. There won't be noticeable differences between H12 an H13 in our home use.

312mm x 282mm x 44mm. Original Samsung filter's HEPA part is 38mm thick after you minus away the activated charcoal portion. It costed me rmb110 each for 4pcs (440 rmb total). He will remember me as I mentioned I will put his contact on a BBS.

It's about 2.8kg or so, so 4PX to Singapore leg is maybe 91 rmb.

China or Korean air purifiers, are they good vs the Sharps, Honeywell, Blueair, IQAir, Austin powerhouses?

Actually, they do test very in-depth in China. Much more in-depth than NEA or CASE.

Summary, they do work ok.





The longer version.

I bought Sharp KC-A50E in the end. I have been wondering, the suction of the air is at the back of the machine. Most people, I believe, will place the air purifier against the wall. If they do so, the suction will be facing the wall. Then why are all the indicators located at the front? What a weird design... Shouldn't the suction face outward towards the room?
