Investing in an air purifier is the first step toward taking control of your indoor air and improving your indoor air quality. But to consistently reap the benefits, regular maintenance is critical. With proper care, Alen Home Air Purifiers are designed to operate at peak performance, ensuring that you're breathing cleaner, healthier air every day.
One might wonder why regular maintenance is so crucial. It's because air purifiers, like Alen's, work tirelessly to remove airborne contaminants, including allergens, dust, pet dander, smoke, and other pollutants. Over time, the filters inside the purifier begin to saturate with these particulates, reducing the unit's effectiveness. Alen is the only company that makes a promise to keep you breathing pure air for life - our Forever Guarantee.
Note that the filter’s lifespan tends to vary depending on what unit you have and how often you use it, so we recommend regularly replacing the filter based on your model’s guidelines or when the filter light turns yellow. For instance, for our Breathesmart 45i model, the filter life is between 9-12 months, whereas for our Breathesmart 75i it is a bit longer at 12-15 months.
Kind of like replacing the oil in your car, regular maintenance involves cleaning the unit and replacing the filters as needed, which directly impacts the purifier's performance. As filters become increasingly saturated, the air purifier must work harder to draw air through the clogged filter, leading to reduced efficiency and potentially increasing energy consumption. The best way to prevent this is by following a regular maintenance schedule, ensuring that the unit operates optimally and has a prolonged lifespan.
How Alen Air Purifiers Work
Employing a combination of simplicity and advanced technology, Alen Air Purifiers efficiently clean the air inside your living or workspace. The process begins when the purifier draws in room air, which is then directed through a highly effective multi-layered filtration system. It begins with a pre-filter that captures large particles like dust and pet dander, followed by a HEPA filter that is key for trapping the finer particles such as pollen and bacteria* as well as other minute particles as tiny as 0.1 micron and smaller. It may also have an activated carbon layer to remove gaseous contaminants such as odors and VOC's (volatile organic compounds).
Each filter comprises high-quality materials, enhancing their capability to capture pollutants. Once the air is purified, it's circulated back into the room, contributing to a healthier indoor environment. This process is repeated numerous times per hour, thereby constantly improving the air quality. Factors such as room size and the specific model of the air purifier can influence the speed and effectiveness of the purification process.
Alen Filters: Options For Your Needs
Just as our air purifiers address a certain room size, the filters below address different types of concerns. Alen provides a diverse array of filter options to meet varied needs. Each filter type addresses a specific set of concerns.
- Essential Filter - medical grade HEPA. Good For: Capturing allergens, dust, bacteria*, and other harmful particles.
- Advanced Filter - Essential + activated carbon. Good For: Absorbing light concentrations of chemicals and VOCs, light cigarette smoke, wildfire smoke, and common household and mold* odors in addition to allergens, pet dander, dust, and harmful particles.
- Ultimate - Essential + odor neutralizer. Good For: Neutralizing pet, diaper, and other stubborn bathroom odors + capturing pet dander, allergens, dust, mold*, bacteria*, and harmful particles.
Alen's Forever Guarantee
The Alen Forever Guarantee is an unparalleled warranty program that covers your air purifier for life. It's a testament to Alen's commitment to quality and durability. This guarantee offers users the reassurance that their device will be repaired or replaced should any issues arise.
Be sure to take note that our Forever Guarantee depends on the use of genuine Alen filters and your adherence to the recommended maintenance procedures. Understanding and complying with these guidelines allows Alen to fully benefit you when using your air purifier.
Making Your Alen Perform at Its Best
Regular maintenance is vital to ensuring that your Alen Air Purifier consistently performs at its best. Over time, as mentioned, the purifier's filter traps a vast amount of particulates from your indoor air, such as dust, allergens, smoke, and even certain bacteria*. As these particles accumulate, the filter becomes saturated, resulting in a decrease in airflow and thus, air purifier performance.
Regular maintenance, which includes periodic filter replacement, ensures that your air purifier can always function at its maximum capacity. With a clean filter, the purifier doesn't have to work as hard to pull air through, leading to more efficient operation. Additionally, regular cleaning of the unit itself helps prevent dust and dirt from entering the purifier, contributing to its overall efficiency.
Preventing A Clog In The System

Infrequent or improper maintenance can have adverse effects on your Alen Air Purifier. First and foremost, a clogged filter can greatly diminish the effectiveness of the air purifier. The device has to work harder to pull air through a saturated filter, which can lead to a decrease in the overall air turnover rate and potentially increase energy consumption.
Moreover, neglecting regular maintenance can also shorten the lifespan of your device. Overworked and overheated due to a clogged filter, the purifier may suffer unnecessary wear and tear. Additionally, failure to use genuine Alen filters or not replacing them as recommended might void Alen's Forever Guarantee.
A Cleaner Home Means A Cleaner Filter: Maintenance Considerations
The environment in which you use your Alen Air Purifier can influence how often you need to perform maintenance and replace the filter. For instance, if the purifier is used in an environment with high pollution levels or in a home with smokers or pets, the filter might need to be replaced more frequently due to a higher rate of pollutant accumulation.
Also, do not use near any source of water such as a sink, bath, shower, or swimming pool. It's essential to keep these considerations in mind to ensure that your air purifier remains effective in purifying your indoor air.
Taking Care of Your Alen so Alen Can Take Care of You
General Maintenance Requirements for Alen Air Purifiers
Maintenance for Alen Air Purifiers mainly includes periodic cleaning of the unit itself and regular filter replacement. How often you'll need to clean the purifier or replace the filter will depend on usage and environmental factors, but a good rule of thumb is to check the filters every 2-3 months and clean the purifier's exterior once a month. Moreover, always ensure that you're using genuine Alen filters that are compatible with your particular model.
How to Clean the Unit Effectively
When cleaning the Alen Air Purifier, first ensure the device is unplugged to prevent any electrical accidents.
To avoid scratching the control panel, do not use abrasive cleaning solutions or scrubbing pads but rather dampen a clean towel with soap and water to clean the control panel, then dry gently with a soft cloth or paper towel. Glass cleaner (e.g. Windex) is also okay to use, but to avoid damaging electronic components make sure you do not allow liquid to seep into the unit. Make sure it is completely dry before plugging it back in.
Detailed Steps on How to Replace the Filters
To replace the filters, you can start by unplugging the unit. However, you don’t need to unplug it if you can’t reach the plug; once you open the front panel it will turn off the air purifier automatically. This is a safety feature. Depending on your specific model, the filter compartment is typically accessed either from the front or back of the purifier. Open the compartment and carefully remove the old filter. It's advisable to dispose of the old filter in a bag to avoid spreading the trapped pollutants. Next, install the new filter, ensuring it fits snugly and correctly. Close the compartment and plug in your air purifier. Remember to reset the filter indicator light on your Alen–hold the filter button for 5 seconds to reset the filter light to green.
Recognizing When It’s Time for Filter Replacement

While the average lifespan of an Alen air filter can last around 12 months, this can vary depending on certain factors and models. For instance our Breathesmart 75i model can last 12 months or longer. Variables such as the size of the space being purified, the air quality of the surrounding environment, and the specific use case of the purifier play critical roles in determining how long a filter will last. In environments with higher concentrations of pollutants or allergens - think of homes with pets, smokers, or locales with heavy pollution - filters may require more frequent replacement, often every three to four months.
Your unit has a filter indicator to alert you of the filter replacement cycle. This filter sensor analyzes air flow, particulates, and more to determine the optimal time to replace your filter. Regularly assessing the state of your air filter and keeping an eye on the filter sensor can be helpful. While these time frames serve as useful guides, each household's air quality and usage pattern can differ significantly. Regular checks help ensure that the filter is replaced as needed, thus maintaining the purifier's optimal performance.
Understanding the Signs of a Faulty or Worn-Out Filter
Identifying signs of a worn-out or overused filter is key to sustaining your Alen Air Purifier's performance. One common indication that a filter needs replacement is a noticeable decrease in the airflow from the purifier. If your purifier's output seems weaker than usual, it's likely that a saturated filter is inhibiting the air passage.
Additionally, an uptick in dust accumulation around your home or persistent odors that the purifier usually removes may also point to a saturated filter. A noticeable increase in allergy symptoms among household members could also indicate that the filter is no longer effectively trapping allergens. Finally, if your purifier seems louder than usual or appears to be working harder, it might be struggling with a clogged filter.
Note that your filter indicator light will first go to yellow, so, if your filter indicator is on red, then it definitely needs to be replaced.
The Importance of the Filter Replacement Indicator on Alen Air Purifiers
The filter replacement indicator is an invaluable feature on Alen Air Purifier models. This indicator eliminates the guesswork involved in filter maintenance by alerting you when the filter needs replacement. When the indicator light is illuminated, it's a signal that it's time to order and install a new filter.
Resetting this indicator following a filter change by holding the filter button for 5 seconds is equally essential as it enables the system to accurately track the lifespan of the new filter. The inclusion of this feature in Alen's design eases the maintenance process, contributing to consistently clean and healthy indoor air. It's a friendly reminder that helps keep your purifier running at its best, safeguarding the air quality in your home.
