Moreover, it is ultra-quiet (25 decibels) like a quiet rural at night time, which completely matches the office environment. In addition, it has 14 color options and an accurate Smart Sensor, timer, and filter replacement indicator.
jane arc reviewed Alen 75i and shared his personal experience as follows,
I have three of these in a 1500 square foot split level apartment. When I moved in to this place, the very next day I developed a severe asthmatic reaction to the local air quality and my neighbors smoking. This led to my being hospitalized and pneumonia. I was not aware the air here was so incredibly bad, or perhaps that I was so very sensitive to it, but I find myself right now debilitated by the air quality outside. I live in a dense urban area on a major traffic throughfare and I get all kinds of noxious garbage from vehicular traffic and all the other joys of city life.
So I initially bought one of these and within minutes I was feeling a bit better. I still wasn’t completely recovered, and I checked out the specs for this unit (it’s expensive, and I was pretty sure I’d bought the biggest one I could). Turns out in order to fully cover my home I actually needed three of these. Well, that’s unfortunate because it’s a lot of bread, but just deciding I’m not going to breathe is not an option. So I didn’t really hesitate in getting two more.
I tell you, waking up in the morning with these things running is amazing. I can actually breathe. My eyes aren’t effed up. I don’t feel like I’m suffocating. I’m not real excited about my neighbors smoking and that getting into my home, but with these running, I have not noticed the smoke once. They’re doing a damn fine job.
One thing I’m very surprised doesn’t seem to be mentioned anywhere is the fact that these are wifi enabled smart devices. I found out on accident while adding a different device to Smart life — I had accidentally added one of these. So I went and added the other two, and now I can control them all from my phone (someone was complaining there’s no remote — okay, but you have a phone, remotes get lost).
One tiny complaint is they’ll report the current air quality, but don’t give you any historical data. It would be personally useful to me to know when and where (which room? Upstairs? Downstairs?) the air quality is worst. It’s a nice to have and I’m fine without it, but if you’re going to be a smart device, that’s kinda cake.
One more thing. I have a Dyson Hot & Cool. It’s a great unit, but when I was gasping for air and thinking the air quality was fine, my Dyson was doing nothing and reported the AQ was fine. Obviously its sensors aren’t very good, or its actual filtration isn’t very good. The air that my Dyson thought was clean was in fact so filthy that I’m using three much larger purifiers to get to the point that I can breathe without my lungs closing up. And that Dyson was $650. There’s no excuse. If you think these are expensive, take a look at the Dyson units and then let it sink in that they literally do not work.
Tough pill to swallow, buying these things, but air is important and life is too short to live with respiratory distress.
The metal body of Alen BreatheSmart 75i is 27 inches in height and 26 inches in width. The bottom-to-top airflow system and 360-degree air intake grill efficiently draw the polluted air in your office or workplace into the air filters.

Moreover, if your office size is up to 1600 square feet, it can clean in one hour. It is CARB certified and best for asthma sufferers or people with breathing issues. Let’s move forward to the Medify Air MA-40-W air purifier reviews.
Erick reviewed Medify MA-40 and shared his personal experience as follows,
I have a 3 year old and a 1 and a half year old sharing a room. They both developed a bit of runny nose and some conditions that appeared like allergies.
My son was taking Albuterol to help with his breathing and wheezing in his chest for a while ( some of my reviews show the inhalers and nebulizers I’ve bought or returned to deal with his breathing issues ). We’ve also been running a cool humidifier next to my son’s crib to help with his nasal issues as recommended by various doctors.
This last time of ending up at the ER with my son leaking from his nose and having heavy breathing was kind of it for me so I decided to try and improve the air quality of their room. We run standard air filters in our home and have very little build up on our fans/air conditioning outlets so I don’t believe it’s a heavy particulate issue, but I said what the hell let me order it.
We received this filter about a week ago and to be honest this was an aesthetic purchase from the pictures. I also really liked the idea of a child proof lock function. The filter is all one unit and fits very nice and snug along the edges. The unit itself look very nice, it’s sleek, with a pretty easy function pad up top. The LED started off with a blue light which means clean air, but once in a while kicks over to green.
During this week both of my kids have been breathing much better, no more runny noses, and per my wife it seems to have worked over about a 48 hour period. I set it to auto and once in a while you hear the fans kick up a little quicker then back to normal. At night, the night mode is a very low hum, almost not noticeable unless you know it’s there.
An added benefit, is that between these two toddlers, at any time in the night or early in the morning after a night of them sleeping and ‘releaving pressure’ from their pre bedtime bottles, it would be like walking into a wall of farts. We have not had to deal with that since putting this air purifier in, so it’s been worth every penny haha.
I’ll be buying another some time for the living room.

Best Air Purifier for Office – Buying Guide
It’s very crucial to first review the most important buying factors before finalizing any air purifier for the office. Remember, choosing the most perfect air purifier model is a daunting task. However; after following these below-mentioned buying factors, it will become quite easier for you to make the right decision.
The capacity of an air purifier is the most important buying factor that determines its efficiency. A reliable air purifier should be capable of handling smaller and larger rooms. You can read the user manual of an air purifier carefully before purchasing it to learn its working capability.
This particular buying factor is often very confusing, however; we will try to keep it simple. We all know that there are several types of filters available in the market, so it becomes very challenging to trust any specific manufacturer and filter type.
HEPA (Highly Recommended for Office Use)
HEPA filtration system is an excellent option for those buyers who are looking for an efficient air purifier. It will effectively trap all the dirt in the air in its high-density filter paper filter to provide you with clean air in the office.
Noise level doesn’t have any active relationship with the working efficiency of an air purifier, but still very important to consider. Most of the air purifiers produce loud humming noise due to their excellent working capability. However; nowadays many latest models produce very little to no noise without compromising on the performance.
Energy consumption is another most crucial buying factor that determines the feasibility of any air purifier. If you are looking for an air purifier for office use, then you must choose those specific models that offer eco-friendly mode and most important energy star certified. Remember, an air purifier should be energy efficient so that you can keep it running in your office all the time for clean air quality.
Filter Change Indicator
If we talk about the office environment, its hectic most of the time and anyone could barely spare enough time to replace the filter. A reliable air purifier must be equipped with a filter change indicator light so that the filter can be replaced on time without disturbing the performance.
A reliable and good air purifier should also offer a Wi-Fi connectivity option so that anyone can track its performance via smartphone. However; it’s an extra feature that has nothing to do with the performance of an air purifier but still it’s better to consider it.
