BreatheSmart 35i
Innovative Features of the BreatheSmart 35i
The 35i offers tremendous value with advanced features that monitor the level of particulate matter in the air. It also features an exceptionally low noise level and is offered at an affordable price. The 35i is the total package, enabling you to reap the rewards of its big performance and smart convenience along with an ultra-quiet, compact profile. This air purifier enables you to create your perfect air without limitations. Let’s drill down on these innovations.
Whisper-Quiet Operation
The 35i takes our commitment to seamless, invisible operation to a new level, emerging as our quietest model yet. With a noise level of just 42 dB at its highest setting, the 35i is nearly silent at speed 1. You can operate it without notable noise disruptions whether you’re working, sleeping, or studying. Remarkably, its silent operation doesn’t compromise its powerful ability. The 35i ensures your air stays clean without disrupting your environment, proving that high performance can be delivered without excess noise.
Advanced Sensors
We’ve designed the BreatheSmart 35i with advanced sensors that track contaminants affecting your air quality. These sensors, which provide real-time data via the Alen app, track the following:
- Particulate matter 2.5 (PM2.5) – Tiny particles in the air that are too small to see with the human eye, including dust, dirt, and smoke that can be inhaled deep into your lungs. Monitoring PM2.5 levels gives you insight into particulate concentration so you know to run your Alen purifier continuously in affected areas.
- Total volatile organic compounds (TVOC) – These harmful materials can come from building materials and household products used almost daily. Monitoring these levels enhances your awareness of when and where these compounds are affecting your air quality so you can take steps to reduce your exposure.
- Equivalent CO2 (eCO2) – These levels indicate your air’s carbon dioxide concentration. If the concentration is too high, you may need to increase the ventilation in your space. Tracking eCO2 levels helps increase your awareness so you can take steps to protect the quality of your air.
- Temperature and humidity levels – Beyond personal comfort, temperature and humidity can affect mold growth and respiratory health. Staying on top of these metrics helps you minimize your risk by keeping your air balanced.
Additional Innovative Features
At Alen, we’re constantly thinking of ways to make your air purification journey better and easier. The 35i’s Auto Light Mode, automatically adjusts the panel lights based on the room's lighting, dimming in darkness and brightening in light. This feature is especially beneficial when you’re in bed about to fall asleep and don’t have to get up to turn off the air purifier’s LED lights. Another innovative feature, smart RFID, makes tracking filter life effortless. You can change between filter types, such as an Essential filter for everyday use or a Advanced filter during wildfire season, without losing track of the original filter’s remaining life. Additionally, Over-the-Air (OTA) firmware updates keep the 35i up-to-date with the latest features, ensuring it stays at the forefront of air purification technology. The 35i enables you to easily optimize your indoor air.
Compact Size/Minimal Footprint
Our most compact smart purifier yet, we designed the 35i to deliver powerful air purification in a small, space-saving package. Whether you just moved to an urban environment and have limited space, are a new family on a budget, or are looking for your first apartment, the 35i packs all the advanced features you need to suit your lifestyle. Its smaller footprint means it fits easily into any space without compromising on performance. Powerful yet compact, the 35i gives you the best of both worlds.
Maximizing the Benefits of the BreatheSmart 35i
Who Benefits the Most?
Many can benefit from the BreatheSmart 35i’s high-performance air purification in small spaces. Whether you’re living in a limited-space environment like a city apartment or dorm room, or on a tight budget, you can have a high-quality air purifier without sacrificing space. If you want to enhance your indoor air quality without giving up a lot of space or spending a fortune, the 35i’s compact size, smart features, and cost-efficiency make it an ideal choice.
The 35i’s filter options are designed to target specific air quality challenges, allowing you to determine how to use it for your indoor air quality needs. The HEPA Essential filter is a great choice for removing allergens and dust, making it ideal for allergy sufferers. The HEPA Advanced filter with an added layer of activated carbon is designed to tackle smoke and light household odors and maintain a fresh environment in kitchens or rooms with pets.
Targeted Pollutants
The BreatheSmart 35i is engineered to target an array of airborne pollutants. For example, it captures PM2.5 particles and smaller, such as dust, pollen, and allergens, making it highly effective for those with respiratory issues. When equipped with a Advanced filter with a carbon layer, the 35i tackles volatile organic compounds (VOCs) that may be released from cleaning products, furniture, or paints. It also captures pet dander and related odors, making the Advanced filter a good choice for homes with pets. Whether dealing with seasonal allergies or everyday pollutants, the 35i tackles various air quality issues.
Where it Works Best Indoors
The 35i works best in small to medium-sized indoor spaces, such as bedrooms, home offices, studio apartments, and dorm rooms. It’s designed to cover up to 1,000 sq. ft., making it an excellent fit for any space that requires powerful yet compact air purification without taking up valuable floor space. Be sure to place it in your home’s high-traffic areas, in shared spaces that would benefit from continuous air purification, or areas that require frequent monitoring.
When is it Best to Use?
The 35i is most beneficial when air quality fluctuates due to seasonal allergies, pet dander, or environmental factors like wildfire smoke. With its low power consumption, it’s also great for everyday use. Whether you want to use it at a specific time or throughout the day and night for continuous clean air, the 35i’s quiet operation means you won't be disturbed. You can even leave your house knowing it will continuously monitor air quality and adjust its performance based on real-time data, putting you in control no matter when you run it.
Understanding the Effectiveness of 35i
Its smart technology allows users to monitor air quality, adjust settings, and schedule usage through the Alen Air app. Using the app ensures that you’re always aware of the air quality in your space and can make adjustments as needed. With its ability to target multiple pollutants, ultra-quiet performance, and minimal footprint, the 35i is a powerhouse air purifier in a compact form, providing real-time air quality improvements wherever it’s most needed. We designed the 35i without sacrificing power, and with four fan speeds and quiet operation, it can work seamlessly in any environment without disrupting your daily routine. Backed by Alen’s Forever Guarantee and OTA firmware updates, the 35i remains up-to-date with the latest technology, ensuring long-term effectiveness in keeping your air clean and safe.
Best Practices for Maintaining the BreatheSmart 35i
Maintaining the 35i is easy. Depending on usage, filter type, air quality, and environmental factors, you may only need to replace the filters every 9 to 12 months. The smart filters take the guesswork out of this process by tracking the filter’s life and sending alerts through the Alen Air app when it’s time for a filter change. If you alternate between filter types, the 35i “remembers” the remaining life of your original filter once you switch back, ensuring efficiency and longevity. Regular filter replacements are quick and keep your air purifier running smoothly.
Along with filter replacements, we recommend periodically vacuuming the prefilter, which can maintain proper airflow. Gently wipe down the outside of the unit and the air vents with a soft cloth monthly to prevent dust buildup. Lastly, check for OTA firmware updates via the Alen Air app, as Alen continuously enhances its products. These updates help keep your BreatheSmart 35i equipped with the latest features and performance improvements. By following these simple maintenance practices, you can ensure that your 35i continues to deliver powerful, smart air purification and enhances the air quality in your home.
