These two models, designed by the reputable manufacturer Shark, are top-of-the-line 3-in-1 air purifiers that can make a significant difference in the quality of the air you breathe.

The Shark Air Purifier 4 is a great option for medium- to large-sized spaces, with a coverage area of up to 1000 square feet.

This model is known for its impressive performance in removing airborne pollutants, thanks to its HEPA filter that captures up to 99.98% of particles as small as 0.1 microns.

Its size and weight make it easy to move around your home, allowing for optimal placement to clean the air effectively.

On the other hand, the Shark Air Purifier 6 is designed for even larger coverage, handling areas up to 1200 square feet.

This model boasts a higher Clean Air Delivery Rate (CADR) than its counterpart, the Air Purifier 4, at 121%.

This means it can remove more airborne contaminants, ensuring a cleaner and fresher environment for you and your family.

Additionally, the Air Purifier 6 comes with a convenient remote control, so you can easily operate it from anywhere in the room.

Both the Shark Air Purifier 4 and 6 models feature a 3-in-1 air purification system: the aforementioned HEPA filter, an activated carbon filter for odor reduction, and a washable pre-filter for larger particles.

These filters work harmoniously to provide you with cleaner, fresher air while reducing allergens and unpleasant odors in your home.

Shark Air Purifier 4 vs 6: Features

The filtration system plays a crucial role in the effectiveness of an air purifier.

Both the Shark Air Purifier 4 and Shark Air Purifier 6 use a True HEPA filter, which is capable of capturing 99.97% of particles as small as 0.3 microns.

This ensures that pollutants like dust, pollen, pet dander, and mold spores are effectively removed from the air.

In addition to the True HEPA filter, these purifiers also feature an activated carbon pre-filter.

This pre-filter helps to reduce odors and VOCs (volatile organic compounds) from the air, improving the overall air quality in your living space.

Clean Sense IQ

One smart feature that both purifiers share is the Clean Sense IQ.

This innovative technology uses advanced sensors to detect and monitor the air quality in your room.

Based on the readings, the purifier will automatically adjust the fan speed to effectively clean the air according to the level of pollutants present.

This means that you don’t have to worry about constantly adjusting the settings manually, as the device will do all the work for you, ensuring your air remains fresh and clean.

Fan Speed and Noise Level

When it comes to fan speed and noise levels, there are some differences between the Shark Air Purifier 4 and 6.

The Shark 4 operates at a lower maximum CADR (Clean Air Delivery Rate) compared to the Shark 6, which means that the latter covers a larger area and offers faster purification.

Regarding noise levels, both purifiers are relatively quiet, but the Shark Air Purifier 6 might be a bit louder due to its more powerful fan.

For most users, this shouldn’t be a significant issue, but if you prefer a quieter environment, especially during sleep, then the Shark Air Purifier 4 could be more suitable for you.

Remote Control and Other Controls

Both the Shark Air Purifier 4 and 6 come with a handy remote control that allows you to manage the device’s settings from afar, conveniently.

This means you can easily adjust the fan speed, turn on the auto mode, or activate night mode without having to get up and physically interact with the unit.

Additionally, both models feature a control panel located on the top of the device that provides touch controls, a filter replacement indicator, and an air quality display.

By comparing these key features between the Shark Air Purifier 4 and 6, you should have a better idea of which model best suits your needs and preferences.
