Honeywell Airgenius 4 Vs 5: Which Air Purifier Should You Buy?

Honeywell Airgenius 4 Vs 5: Which Air Purifier Should You Buy?

The AirGenius 4 and 5 are intelligent air purifiers with HEPA filters but differ in performance and features. Let’s look at how they compare to see which is right for you.

The Air Genius 4 by Honeywell

The AirGenius 4 is a compact air purifier used in any room. Its advanced filter technology uses HEPA and carbon filters to remove 99% of airborne particles, including allergens, dust, mold spores, and pet dander. The unit also features an activated charcoal odor filter that removes odors from cigarette smoke, cooking, and pets.

It has a built-in ionizer that purifies the air by emitting positive and negative ions. This helps remove odors, allergens, and other pollutants from the air so they can’t cling to walls or furniture. The unit also includes an auto mode that automatically changes settings based on your needs. When it detects smoke, it switches to high fan speed; when there’s not much particulate matter in the air, it lowers its fan speed.

The AirGenius 4 also comes with a remote control and an LCD that shows you how much time is left in the cleaning cycle, how many times it’s been used, filter status, and more.

Air Genius 5 by Honeywell

The AirGenius 5 is a powerful air purifier designed to filter out large particles, chemicals, and odors from the air. It comes with a HEPA filter that traps 99.97% of particles as small as 0.3 microns in size. You can set it to automatically change settings based on your needs or use the remote control or LCD to control it manually.

It also has a carbon pre-filter to help neutralize odors and chemicals, an ionizer to attract dust particles, two fan speeds, and an automatic mode. The unit has a built-in night light feature and is Energy Star certified. It’s available in sizes 30″, 36″, and 42″.

This cleaner is lightweight and slim, making it easy to move around. It comes with two different filters: one pre-filter and one HEPA filter. The pre-filter helps neutralize odors and chemicals, while the HEPA filter traps 99.97% of particles as small as 0.3 microns in size. You can set it to automatically change settings based on your needs or use the remote control or LCD to control it manually.

Honeywell Airgenius 4 Vs. 5 Comparison

The AirGenius 5 has several advantages over the 4. It has a larger capacity and can filter twice as much air per minute (150 cm vs. 75 cm). It also has a better design, making it easier to assemble, disassemble, and move around. The HEPA filter lasts up to three years longer than the AirGenius 4 model.


AirGenius 4 and 5 are two smart air purifiers from Honeywell. They have a sensor that detects the level of air pollution in the room and automatically adjusts their fan speed based on it, ensuring you’re getting the most out of your cleaner. The AirGenius also has an auto-off timer, which can turn off after 1 or 7 hours, giving you more energy-efficient options for your home setting.

Model 4 is an air purifier that can filter up to 400 square feet, making it an excellent choice for bedrooms and small living rooms. The filter traps particles like dust, pollen, pet dander, and smoke in its HEPA-grade filter. This means you’ll breathe clean air, free from any chemicals or allergens.


The Airgenius 5 is better for medium to large rooms. It has a higher CADR (Honeywell’s term for its filter efficiency), so this unit will clean more dust, allergens, and odors from your home’s indoor air. It also has two-speed settings, which means that if you want to run it on low power for a quieter operation, it will still filter your home’s air effectively.

The Airgenius 4 works best for small to medium and only has a one-speed setting. It is also louder than model 5.

Both units are effective at purifying the air in your home, but you’ll want to choose which one is right for your space based on how big of a room you want it to cover.

Air Quality Control

The Honeywell AirGenius 5 and the AirGenius 4 purifiers come with intelligent sensors that can automatically adjust their settings depending on your location, whether at home or away. Both also have a “smart” mode that uses the device’s high-quality filters to trap dust, pollen, and microscopic particles in the air. However, there are some differences between how effective these two modes are.

The AirGenius 5 has an advanced “Smart Mode” system that automatically optimizes itself for different types of environments, including home and office spaces; this means it can be set to different levels depending on what kind of space you want to use it in (i.e. if you want less noise while watching TV). On top of that, it also has an Auto mode that adjusts its settings based on your activity level, so you don’t even have to think about turning anything on or off!

The older version (4) only comes with basic modes that cannot be customized beyond changing fan speeds or adding upholstery filter pads as needed – but since they’re both so good at what they do already, there probably won’t be much difference here either way!


Model 5 comes with a 3-year warranty on the motor and one year on the filter and fan. Model 4 has a 5-year motor and filter but only a 1-year warranty on its fan. Both have a 2-year warranty on their air purifier accessories (like remote controls).

Both models also have a one-year guarantee against manufacturing defects.

Honeywell Airgenius 4 Vs. 5 – Conclusion

Both air purifiers are intelligent and effective air purifying units. The only significant difference is that the AirGenius 5 is better for medium to large rooms, whereas Model 4 is best for small to medium rooms.

AirGenius 4 is smaller, but it still provides you with enough filtration area in your room. It also has a lower CADR rating than its bigger brother. If you want something more efficient at removing harmful pollutants from your environment, you must get yourself an AirGenius 5 instead.
