Samsung AX7000 Air Purifier 4 5
BGR Rating :


  • The Samsung AX7000 Air Purifier is priced at Rs 60,000, while the smaller AX3000 retails at Rs 24,000.

  • It can clean the air in a 1000-square foot space in about ten minutes.

  • This air purifier is particularly useful if you have a large home and live in a place where air pollution is a concern.

I’ve used air purifiers for a while now. It started with my wife’s allergies acting up, which prompted us to buy one for our home. A couple of years ago, we bought the Xiaomi Mi Air Purifier 2. It’s still one of the most effective affordable options around. For its modest Rs 8,999 price tag, the Mi Air Purifier 2 has certainly added much more value to the quality of my wife’s health. On the other hand, I’m fortunate to not suffer from allergies; and yet, when the air purifier is running, I enjoy the feel of clean, pure air.

That’s essentially the point of an air purifier. It directly benefits people with allergic conditions, but for the rest of us the benefits aren’t visible or necessarily immediate. You’re breathing cleaner air, and that’s benefiting you in the long run. And while you can’t live your life in the purified air of your home, you are reducing your chances of illness by placing an air purifier in the place where you presumably spend most of your time.

Air purifiers do this by capturing fine and superfine particulate matter from the air, trapping it within the filter and pushing out the clean air. There are two types of particulate matter commonly considered as harmful in populated areas – PM10 and PM2.5. While PM10 refers to larger particles of 10 micron diameter, PM2.5 is considered the more harmful one for humans. With a diameter of 2.5 microns, it’s small enough to escape through the natural defenses of your nose and throat and go straight to your lungs or circulatory system. This is obviously harmful, and is the reason why pollution is bad for us. It’s these particles that air purifiers aim to capture and prevent from entering our systems.

Does size matter?

While affordable air purifiers are usually smaller and don’t have as many fans or as much filtration area, expensive purifiers offer this benefit through product size. Today we’re reviewing the Samsung AX7000 Air Purifier, which is one of two new products in the company’s range of air purifiers launched in India. It’s priced at a not-so-affordable Rs 60,000, while the smaller AX3000 is priced at Rs 24,000. You could potentially get both of these products for significantly less in physical stores, so it makes sense to look around.

The reason why the Samsung AX7000 costs as much as it does is down to its size and capabilities. The device stands tall at about four feet in height, and therefore needs a suitable spot in your home where it can intake air and push it back out. The front of the air purifier is a grille which hides a four-step HEPA (high efficiency particulate air) filtration system powered by two fans that pull in air. The cleaned air is then pushed out through three vents (at the top, left and right). When powered on, the flow is so strong that you could well use the air purifier as a personal fan if you sit right next to it.

The power of the fans and four-step filtration system means that the Samsung AX7000 air purifier is rated to purify rooms as large as 93 square meters (about 1,000 square feet). When I opened up all the doors of my 700 square-foot apartment, the purifier was indeed effective enough to clean all the air quickly and effectively. It also has the distinct advantage of deodorizing thanks to the special filter for that purpose.

We did experience this when we returned home after a short trip to that stale musty smell, since the house had been shut for a few days.  The air purifier was effectively able to knock out the smell in about ten minutes of being switched on.

Display, sensors and all that

In order to aid the visual aspects of watching an air purifier at work, the Samung AX7000 has a display that shows the PM10 and PM2.5 levels along with other useful information. The touch panel at the top lets you control power, fan speed, turbo filtration, ionization, timer, child lock and particulate matter levels for PM10 and PM2.5. While competing products don’t have an on-device display, this is a big advantage of the Samsung AX7000. It gives you real-time, uncomplicated visuals detailing exactly what the system is doing.

This helps in one key way – you don’t need to connect the air purifier to your internet at home and control it through an app. While this seems counter-intuitive, a device such as an air purifier is better controlled and used manually in my opinion. While IoT air purifiers have the advantage of being remotely turned on and off, the Samsung AX7000 does unfortunately miss out on that being an unconnected device.

However, it does to some extent make up for this with its timer system. Once you turn on the air purifier, you can set a timer starting from one hour on when the air purifier should automatically turn itself off. This will ensure lower power usage and optimal wear-and-tear on the air purifier itself – the filtration system has a limited shelf life and will need to be replaced when it loses its effectiveness. Replacement filter kits can of course be purchased from Samsung directly, and the life of the filter depends entirely on how much you use the air purifier.

In my case, I didn’t have the air purifier running all the time, as is recommended. This is because I live in a particularly green part of Mumbai, and have less pollution to worry about than most people. Users in Delhi where pollution is particularly menacing may need to run their air purifiers all the time, especially if you have certain windows that don’t close completely or gaps in homes that would constantly allow outside air to enter.

The key to proper use of an air purifier is to have a sealed home, preferably one that is air-conditioned continuously. Indeed, when I opened up the windows while the Samsung AX7000 was on, the particulate matter levels would immediately spike, as soon as the new air would make contact with the sensors. The color-coded system of the air purifier would immediately make the display go orange and eventually red as the particulate matter levels would rise. With the windows open, you’re drastically reducing the efficiency of the purifier.

However, with the windows closed and the seal maintained, the sheer power of the purifier does wonders. Within minutes, you’ll see both PM10 and the more harmful PM2.5 levels drop, and the filtration system cleans the air and pushes it back out. During my review, it usually took about ten minutes to completely clean the air in my house and bring PM2.5 levels down to the device’s display limit of 9 micrograms per cubic meter. It’s possible that levels have dropped below 9 micrograms, but the Samsung AX7000 is hardware-prevented from displaying a reading below that.

I did on many occasions succeed in bringing both the PM10 and PM2.5 levels down to 9 micrograms per cubic meter or less, thereby breathing some incredibly clean air for the city. On cool days, it almost felt like I was in the hills breathing pure air. Of course, switching off the purifier for even a couple of hours brings the levels back up as particulate matter sneaks into the room through any small gaps that may be present.

Verdict – Do you really need a Rs 60,000 air purifier?

Air purifiers certainly help people with respiratory and allergic conditions. Clean air at home can only help you. But an air purifier that costs Rs 60,000? Yes, that might be a bit much. When you can get the Xiaomi Mi Air Purifier for Rs 8,999, Rs 60,000 does seem like a lot. It’ll certainly benefit large rooms, and is necessary if you’re looking to clean the air in a big living room or even a small but relatively evenly-shaped home. However, it’s a limited requirement for a relatively niche segment as it is, so you’re unlikely to need an air purifier of this size. The smaller AX3000 model might serve you fine for a regular-sized room.

However, if you do choose to invest Rs 60,000 in the Samsung AX7000 air purifier for whatever reason, rest assured that you’re getting one of the most powerful products of its kind available in India. It’s big, effective and quick, cleaning the air in a medium-sized space is a matter of minutes, and keeping it that way. It’s undoubtedly the best air purifier we’ve experienced, purely for the raw power on offer.
