Best Air Purifiers to Buy in Amazon Great Indian Festival 2021 Sale

Published

on

With the Amazon Great Indian Festival you can get great offers and discounts on air purifiers right now, and we’ve picked out the best ones that you should be looking at. Air Purifiers are now a necessity and not a luxury specially if you live in cities where winter brings in a fresh wave of air quality issues, which intensify over the next few months. Of course, with a huge number of air purifiers on the market, finding the right ones to buy is tricky and with the deals on offer it can be even harder to pick.

We can help narrow down the decision with a few different deals that we’ve noticed in the sale. We’ll also break down the things that you need to consider when buying an air purifier. We’ve broken down the workings of how to buy an air purifier, but at the most basic level, you’ve got a fan, that sucks polluted air into the purifier, pushes it through filters (called HEPA filters) that clean up the suspended particles like pollutants and germs, and the pushes it out again into the room. This process of scrubbing the air clean is measured by the CADR or Clean Air Delivery Rate of your air purifier, and the higher the number, the faster that the air is being cleared.

Therefore, when buying an air purifier, the two things to make sure are that it is using a HEPA filter to more effectively clean the air, and whether the CADR is high enough for your purposes. The bigger a room is, the higher the CADR that you need. The American Association of Home Appliances Manufacturers recommends a CADR that’s 2/3 the size of the room — and Fuji has presented a helpful table that lets you see what the minimum CADR is for your requirements.

Philips is one of the companies that has been a frontrunner in air purifiers for the last several years — when the air pollution levels reached a crisis point in North India, Philips was one of the first companies to have a full range of consumer products for clean air, and it remains one of the leaders in this technology space even today.

It has a range of air purifiers starting from under Rs. 10,000 to under Rs. 40,000 — these have a number of different features but more importantly the CADR differs between the models, so take that into account along with the size of your rooms, when making a purchase.

Published

on

Xiaomi unveiled its first humanoid robot named CyberOne alongside the Xiaomi Mix Fold 2 during a live event on Thursday.

Polycab Hohm Mirai Smart IR Blaster Review: Make Appliances Smart Again

Published

on

Polycab is best known for its industrial-grade electrical cables and wires, but the company has also recently expanded into the field of home appliances such as fans, lighting, and switches. The company’s latest foray is into smart home and home automation solutions, with its Hohm range of IoT products. The product I’m reviewing today is the Polycab Hohm Mirai Smart Infrared Blaster, a small device which allows you to control traditional IR-based appliances with a smartphone app or voice commands.

Priced at around Rs. 1,200 in India, the Polycab Hohm Mirai Smart IR Blaster is a compact, uncomplicated device that can be used to add smart controls to not-so-smart IR-based appliances such as air conditioners, televisions and set-top boxes, fans, and audio equipment, among others. How does this device work, and is it effective at making your home appliances smart? Find out in this review.

What is the Polycab Hohm Mirai Smart IR Blaster?

The Polycab Hohm Mirai Smart IR Blaster is a rather simple, unassuming device to look at. It’s a small black box with the ‘Hohm’ logo on the top, an indicator light at the front above the IR emitter, and two Micro-USB ports — one at the back and one at the bottom — either of which can be used to power the device. There is also a hook on the underside to wall-mount the device, if needed.

Included in the sales package of the Polycab Hohm Mirai is a USB Type-A to micro-USB cable, and a power adapter to connect to a wall socket. Once powered up, the device will need to be positioned such that the IR emitter points at the receiver of the appliances that need to be controlled. There is no power switch, but there is a pinhole for the hard-reset button, and a 3.5mm socket at the back. The latter can presumably be used with a compatible IR emitter accessory to extend the range and angle of the IR beam, but the accessory for this isn’t included in the box.

The Hohm app (available on iOS and Android) is used to set up and control the Polycab Hohm Mirai Smart IR Blaster. The process to install the Mirai Smart IR Blaster was fairly simple, and I was able to connect it to my Wi-Fi router quickly and without any trouble by simply following the steps on the screen. The device is only compatible with 2.4GHz Wi-Fi, and it maintained a stable connection with the router during my review.

How does the Polycab Hohm Mirai Smart IR Blaster work?

Once setup was completed, the app showed ‘Smart IR’ as a device in the app; if you have any other Hohm-compatible devices, they’ll appear here as well. The Mirai Smart IR Blaster itself can control multiple IR devices, which can be set up within its device listing. The list of supported devices includes televisions, set-top boxes, air conditioners, fans, lights, projectors, audio and DVD players, heaters, and purifiers across a huge list of global brands.

In the rare scenario where your IR device isn’t on the list, there is also a process to ‘teach’ the Polycab Hohm Mirai Smart IR Blaster the specific IR signal for your devices, using the DIY or ‘Learn Match’ methods in the app. I tested the Hohm Mirai Smart IR Blaster with an Atomberg remote-controlled ceiling fan and Carrier air conditioner in my home, both of which were part of the list of supported devices and could be set up easily using preloaded profiles.

For the Atomberg fan, I had to manually set up additional buttons on the remote by ‘training’ the Polycab Hohm Mirai Smart IR Blaster; this involved pointing the Atomberg fan’s remote at the Hohm device and pressing the buttons to give it instructions on how to interact with the ceiling fan.

Once done, the button interface in the app for the Atomberg fan was a bit messy and had a bunch of unnecessary buttons, but I was able to control all the desired functions as needed. The air conditioner’s button interface was a lot cleaner, and had all key functions available without any further intervention on my part. Usefully, the Hohm Mirai IR Blaster was able to control both devices from a single convenient angle in between the two appliances, so its infrared range is quite wide and the beam is suitably powerful.

You can also link the Polycab Hohm Mirai Smart IR Blaster to Alexa or Google Assistant, and operate the device and any configured appliances with voice commands either through your smartphone or smart speakers. This worked reasonably well on both voice assistants to turn on or off the devices, but more complicated functions such as adjusting the fan speed were not supported through voice commands, and could only be controlled using the app.

It’s also possible to create automation routines through the Hohm app, based on factors such as weather conditions, your location (such as when you leave your home), and timed schedules, among other things. It took a bit of effort to create certain routines, but once done this feature worked as expected, and some of these routines were even supported by Alexa and Google Assistant for voice controls.

Verdict

The Polycab Hohm Mirai Smart IR Blaster is the perfect answer for anyone who has had to deal with the frustration of getting up and finding the remote for a device or appliance in their home. It’s easy to set up, supports a wide variety of IR-controlled devices, can be controlled via popular virtual assistants, and works reliably. Although the app interface isn’t perfect, there’s always a way around, which is easy enough to find. The Hohm Mirai successfully does exactly what it’s designed for — make non-smart appliances smart.

At Rs. 1,200 or so, it’s inexpensive, and very flexible since it can control multiple devices in the same room and enables voice controls or automation routines too. However, the most important point here is its reliability, and the Polycab Hohm Mirai Smart IR Blaster checks this box to earn my recommendation.

Rating: 9/10

Pros:

  • Easy to set up and use
  • Works with Alexa and Google Assistant
  • Supports lots of IR-based appliances
  • Can be used with multiple devices in the same room
  • Reliable, does what it’s supposed to do

Cons:

  • Somewhat awkward UI with some appliances
