If you only own one air purifier, the ideal place to put the unit is in your bedroom. This is the room in your home where you spend the most time out of each day. An air purifier in the bedroom can contribute to a better night's sleep by reducing the allergy symptoms that make a good night's sleep difficult. In addition, the white and pink noise produced by an air purifier can help you sleep more soundly.
Try to keep your unit at least one foot away from walls and furniture, and never block the air entrance and exit vents. This will allow air to circulate properly around the room and into the air purifier.
For Tower units, directing the air out into the room is best. Do not direct the clean air at a wall or furniture, as this can interrupt the airflow in the room. For box units that direct air upwards, do not place them under a table or shelf, which can block the airflow. Allowing the airflow to blow to the ceiling is best, as it will circulate along the ceiling and around the room, bringing dirty air back towards the unit.
We recommend that you run your air purifier 24 hours a day. Although an air purifier may clean a room up to 95% in only an hour, it can only keep the room clean while it is running. In a home with a HVAC system circulating air, the air coming out of your vents will be significantly dirtier than the air in the room with the air purifier. The filters in HVAC systems in homes or offices are not meant to purify the air for you to breathe, but only to remove the largest dust particles to protect the mechanical operation of the HVAC system. Over time, the HVAC system accumulates dust particles in the vents and ducts. When it turns on, it will be circulating this dust throughout your house. You will notice the best results from your air purifier when it can catch the dust and other particles as your HVAC system runs.
However, if running your air purifier 24 hours a day isn’t practical for you, you can take certain steps to maximize its performance while running it less often. Consider the following example: A unit rated for 750 square feet can reduce the airborne particles by 95% in less than 60 minutes in a room of 375 square feet. For a room rated at the maximum coverage area of the unit, such as 750 square foot room, you must let the unit run for twice as long to clean the air. Once you have run the unit on high and cleaned the air in the room, do not turn it off or the air will quickly return to pre-cleaned levels in as little as 3-4 hours. Instead, you should turn the unit down to speed 2 or 3. This will be high enough to maintain clean air in the room. If you do turn the unit off, then the next time you turn it on, you should follow the same step as if you placed the unit in a new room: turning to the highest speed for at least an hour.
This is a common occurrence based on room conditions, placement, and unit features.
The air in each room is not homogeneous, so different pockets of airborne particles (like dust and pollen) circulate to different areas based on activity.
BreatheSmart units also have different numbers of color rings:
- 75i (5)
- 45i (4)
- Classic & FIT50 (3)
The speed you use should correspond to the room size that you have placed the unit in. If you get a unit rated up to 750 square feet, this means 750 square feet of coverage on the highest speed. Using it on a lower speed will take longer to clean the room.
All of Alen’s air purifiers are non-ozone producing and as such, there won’t be any health consequences or other side effects. All our air purifiers do is circulate the air in the room and filter it, leaving it clean; they will never add anything to the air in your room. If you’re still shopping around for air purifiers, it’s important to note that you should never choose a purifier that emits odors, chemicals, or ozone. These can be harmful, particularly in people who are chemically sensitive.
Many people wonder if they’ll notice a big change on their energy bill after they start using their air purifier. Since our purifiers are engineered to be as energy-efficient as possible, you should not notice a significant uptick. HEPA air purifiers typically consume 50 to 200 watts of electricity, which is about the same as a lamp (60 watts) and significantly less than a plasma tv (240 watts). Appliances like your refrigerator, which run continuously at 500-750 watts, will have a much greater impact on your energy consumption.
The other major cost associated with air purifiers is that of replacing the filter. The frequency of filter replacement can vary, but with normal use, you’ll probably be replacing your filter every six months. To save money, consider purchasing multiple filters at once for bulk discounts, or save money with our filter subscription service.
Since air purifiers cannot work through walls, there should be one in each room you’d like to focus on. We recommend keeping one unit in the bedroom and one in the most high-traffic area of your home, at minimum. If you have a particularly large living area, you might find it more effective to use two smaller units positioned at opposite ends of the room.
In general, Alen air purifiers are notably quiet; however, they will grow louder on higher speeds. If you’re concerned about noise, run your air purifier on high when you’re not in the room, or ask one of our experts about which units are the most quiet. Many people find that they enjoy the white or pink noise from the air purifiers, especially at night.
Many of our air purifiers have monitors that will tell you when they are “ramping up” in response to changes in air quality in the room. When it’s time to change your filter, you may also notice visible particles on the filter. If you suffer from allergies, you should be able to notice the positive effects of fresher air within a day of using your unit.
Prefilters are the fabric layer that covers the exterior of your filter. Your prefilter is designed to capture larger particles such as dust and hair. Think of your pre-filter as the first line of defense against airborne contaminants.
On the 75i, the prefilter is a white screen material. All other purifiers use a black felt-like material. These prefilters attach to your filter using Velcro-like strips for easy removal and replacement. We recommend cleaning by vacuuming only, but not washing.
Alen pre-filters are now stronger, longer lasting, and easier to clean. Committed to innovation and improvement, we believe durability goes hand-in-hand with purifying performance.

Most of our air purifiers have an electronic indicator that will tell you when it’s time to change your filter. If you are using a model that doesn’t have an indicator, you might notice that your air purifier is working harder than usual, indicating that it’s trying to pull air through a clogged filter. For normal use, expect to change your filter every six months.
Change your air filter as soon as possible after your indicator light comes on. As filters become dirty, the air purifier has to work harder and harder to move the air through them, which drastically decreases your air purifier’s effectiveness.
Keeping your windows open for long periods of time may temporarily reduce the effectiveness of your air purifier, but we encourage you to open your windows and mix in some fresh air whenever you like.
Although air purifiers can reduce the harmful effects of breathing in mold and possibly prevent mold in the future, they cannot eliminate an existing mold problem. Mold can be a dangerous concern, and should be taken seriously and professionally removed prior to purchasing an air purifier.
