Access to clean, unpolluted air is vital for our health and well-being. It's a basic need that often gets overlooked, especially as we spend so much of our time indoors. The quality of indoor air can have a significant impact on our health. In fact, the Environmental Protection Agency (EPA) states that indoor air pollution levels can be 2-5 times higher than outdoor levels, highlighting the need to address this issue seriously.

Air pollution comprises a myriad of particles and gases, each having its own unique impact on our health. Fine particulate matter, volatile organic compounds, and biological pollutants like mold spores and bacteria are among the common culprits. Over time, continuous exposure to these pollutants can lead to a variety of health issues, ranging from mild irritations, like sneezing or coughing, to more serious conditions, including respiratory diseases, heart problems, and even certain types of cancer.

Air purifiers have become an essential tool in the fight against indoor air pollution. These devices work by filtering the air, removing harmful particles and gases, and thereby improving the overall air quality. Different models of air purifiers are designed to target specific types of pollutants, making them an efficient solution to address a range of indoor air quality concerns. Whether you're dealing with allergens from pets, fumes from cooking, or off-gassing from furniture and cleaning products, there's an air purifier designed to handle it.

Understanding Air Pollution

Air pollutants, typically divided into three main categories: particulate, gaseous, and biological pollutants, all have unique characteristics and sources.

  • Particulate pollutants: These are tiny particles or droplets suspended in the air. They can include dust, soot, smoke, and liquid droplets. Some particulates are large enough to be seen with the naked eye, such as dust and dirt, but others, like fine particles from burning fossil fuels, are so small they can only be detected with an electron microscope.
  • Gaseous pollutants: These include gases such as carbon monoxide, sulfur dioxide, nitrogen oxides, and volatile organic compounds. These gases are often produced through burning fossil fuels, industrial processes, and certain household or commercial products.
  • Biological pollutants: This category includes living organisms like bacteria, viruses, mold, fungi, pollen, and pet dander. They are typically associated with damp and humid environments and areas that are not regularly cleaned.

Common Indoor Air Pollutants And Their Sources

  1. Dust, allergens, and pet dander: These common particulates are usually present in all indoor environments. Dust can be produced by fabric, furniture, and human activity, while allergens and pet dander are generated by animals.
  2. Pollen, mold spores: These biological pollutants are typically carried into the home from the outside, but mold can also grow indoors in damp areas. Pollen levels are typically higher during certain times of the year, while mold can occur year-round if the conditions are right.
  3. Volatile organic compounds (VOCs): VOCs are a type of gaseous pollutant that can off-gas from a variety of materials and products, including paint, cleaning supplies, building materials, and furniture. These compounds can linger in the air and cause a variety of health problems.

The Impact Of These Pollutants On Human Health

Exposure to these pollutants can have a significant impact on human health. Short-term effects can include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Long-term exposure can lead to respiratory diseases, heart disease, and even cancer. Those with existing health conditions, such as asthma or allergies, may also experience worsening symptoms when exposed to these pollutants.

Alen Air Purifiers: An Overview

Our air purifiers play a significant role in improving indoor air quality by reducing or eliminating various pollutants. We offer four different filter types to address your unique needs. They are particularly beneficial for people with allergies, respiratory conditions, or those who are particularly sensitive to air quality. Besides improving health, air purifiers can also help remove odors, creating a more pleasant living or working environment. When purchasing an Alen air purifier, we recommend you select a product that is the right size for your room, and the choose the filter for your needs.

Working Mechanism of Alen Air Purifiers

Alen air purifiers operate through a comprehensive process that's designed to ensure maximum air purification. They function by employing a multi-stage filtration system that is effective at removing a wide range of pollutants.

First, Alen air purifiers draw in air from your living or working space. This air, filled with a multitude of particles, is then subjected to the first stage of filtration. Alen air purifiers often feature a pre-filter, which is designed to capture larger particles such as dust, hair, and pet dander. This not only helps in improving the overall air quality but also protects and extends the life of the subsequent filters.

Following the pre-filter stage, the air then passes through a High Efficiency Particulate Air (HEPA) filter. Alen's True HEPA filters are designed to capture 99.97% of particles as small as 0.3 microns, effectively eliminating most allergens, tiny dust particles, and mold spores from the air.

We have 4 different filter types:

  • Pure filter - medical grade HEPA. Good For: Capturing allergens, pet dander, dust, mold, bacteria, and germs 
  • Fresh filter - Pure + activated carbon. Good For: Absorbing light concentrations of chemicals and VOCs, light cigarette smoke, wildfire smoke, common household and mold odors in addition to allergens, pet dander, dust, mold, and germs 
  • VOC/Smoke Filter - HEPA + maximum activated carbon/  Good For: Absorbing heavy concentrations of chemicals and VOCs, heavy cigarette smoke, wildfire smoke, common household and mold odors in addition to allergens, pet dander, dust, mold, and germs 
  • Odor Filter - Pure + odor neutralizer.  Good For: Neutralizing pet, diaper, and other stubborn bathroom odors + capturing pet dander, allergens, dust, mold, bacteria and germs 

The Fresh, Smoke, and Odor filters have 3-stage filtration - pre-filter, HEPA, and either Carbon, more carbon or Odor Neutralizer. The Pure Filter has 2 stages - Prefilter and HEPA

For gases and odors, Alen purifiers use an activated carbon filter. This filter is made from small, porous granules of carbon that are extremely efficient at trapping volatile organic compounds (VOCs), tobacco smoke, cooking odors, and other gaseous pollutants.

In all models, Alen air purifiers include an ionizer that can be manually switched on or off by the user. The ionizer releases negative ions that bind to positively charged particles like dust, pollen, and bacteria, forming heavier particles that either fall to the floor or are more easily captured by the HEPA filter on the next pass through the purifier. Alen’s air purifiers do not emit ozone and they meet the most stringent specifications, like those of the California Air Resources Board (CARB).

The cleaned air is then propelled back into the room, contributing to a healthier and cleaner environment. This entire process is performed multiple times an hour, continuously cycling the room's air through the purifier and progressively reducing the concentration of pollutants. This diligent purification process, tailored for various pollutant types, ensures that Alen air purifiers deliver cleaner and healthier air in your indoor spaces.

Maintenance Requirements for Alen Air Purifiers

Maintenance for Alen air purifiers is straightforward. The primary task is filter replacement, which is recommended every 6, 9, or 12 months for typical use. The exact duration can vary based on the air quality in your home and how often you use the purifier. Most Alen models have a filter life indicator, which alerts you when it's time to change the filter. It's also advisable to regularly clean the exterior of the unit using a dry, soft cloth. 

Customer Reviews and Ratings of Alen Air Purifiers

Alen air purifiers are highly regarded by customers for their performance, durability, and design. On major retail and review sites, Alen models frequently receive high ratings, often 4.5 stars or above out of 5. Customers have praised the purifiers for their quiet operation, efficiency in allergen removal, and aesthetic appeal. The BreatheSmart 75i, in particular, is often lauded for its high capacity, capable of purifying larger rooms quickly and effectively. Consumer Reports has also named the Alen 75i as the Best Overall air purifier for 2022 and 2023.

As with any product, experiences do vary, but the overall consensus is that Alen air purifiers are a reliable and valuable tool for improving indoor air quality. 

Factors to Consider When Choosing an Alen Air Purifier

Selecting the right Alen air purifier involves considering several factors. To start, assess the types of pollutants you are primarily concerned about. Are they particulates, gases, or biological contaminants? Alen offers models that excel in dealing with each of these categories. 

Next, consider the size of the room where the air purifier will be used. Different models are designed for different room sizes, so it's crucial to match the purifier's capacity with the room's square footage.

Finally, consider factors like noise levels, energy efficiency, aesthetics, and cost. Alen's variety of models means you're likely to find one that ticks all your boxes.

To make it easy, we offer a handy tool that will determine the right air purifier for you.  

Considerations for Placement of an Alen Air Purifier

Placement of your Alen air purifier can significantly impact its effectiveness. As a rule of thumb, your air purifier should be placed in an area where airflow is not obstructed, preferably away from under tables, behind drapes, furniture, and in tightly confined spaces. 

The unit should also be located where it can serve the most people, such as the living room. If you’re using your Alen air purifier in the living room, the best placement is next to the wall opposite the couch or chairs.

If allergies or asthma are a concern, it could also be beneficial to have an air purifier in the bedroom, as we spend a significant portion of our time sleeping.  If you’re using it in the bedroom, the best placement is next to the wall opposite of the headboard to achieve the best circulation and filtered air when you sleep.

Additionally, if you're dealing with specific pollutant sources like a cooking area or smoking room, placing the purifier in or near those areas would be beneficial.

Instructions on Replacing Filters and Ensuring Optimal Performance

Maintaining the optimal performance of your Alen air purifier is primarily achieved by regular filter replacement. Filters should typically be replaced every 6, 9, or 12 months, but check the filter life indicator on your unit for more precise timing.

Replacement involves turning off and unplugging the unit, removing the front panel, taking out the old filter, inserting the new one, and replacing the panel. Always follow the specific instructions provided in your model's manual.

To further ensure optimal performance, remember to keep the unit clean and unobstructed to allow for proper airflow. With regular maintenance, your Alen air purifier will continue to provide cleaner, healthier air for you and your family. We also recommend our filter replacement subscription service which will ensure you always have a new filter when needed.
