Controls and connectivity
App connectivity
Austin Air HealthMateNo score yet
Levoit P350-P
2.1
App control is a clear weakness. Reviewers repeatedly point out that the P350 lacks app connectivity, scheduling through an app, and air quality readouts.
Voice assistant compatibility
Austin Air HealthMate
2.0
Voice assistant evidence is limited to a complaint that Alexa-style connectivity is absent.

Other features
Breathing relief
Austin Air HealthMateNo score yet
Levoit P350-P
4.5
Many owners describe easier breathing, fewer asthma or sinus issues, less congestion, and cleaner-feeling air after running the purifier. The strongest praise comes from pet-allergy and respiratory-irritant situations.
Child lock

Levoit P350-P
4.2
The pet lock is appreciated by owners with pets or children, but it is not foolproof for every home. One cat owner said their kittens still managed to interfere with the controls.
Control placement

Levoit P350-P
4.6

Initial chemical smell
Austin Air HealthMateNo score yet
Levoit P350-P
3.5
Most owners do not report chemical or strange smells, and a few specifically praise the lack of odor from the unit. A small number had the opposite experience, including a foul smell after a few months.
Ionization feature
Austin Air HealthMateNo score yet
Levoit P350-P
4.6
Reviewers who mention ionization treat its absence as a plus, especially around pets and ozone concerns. Experts also describe the filtration system as ozone-free without ionizer or UV-C stages.
Mold spore reduction
Austin Air HealthMate
4.5
Mold-related evidence is limited but favorable, with one expert-style claim and one mold-allergy owner endorsement.
Levoit P350-PNo score yet
Ozone-free operation
Austin Air HealthMateNo score yet
Levoit P350-P
4.5
Ozone-free operation is viewed positively by pet owners and headache-sensitive users. Reviewers liked that it avoids ozone or ionizer features while still improving air quality.
PM2.5 detection
Austin Air HealthMateNo score yet
Levoit P350-P
4.7
PM2.5 results are strong in expert testing, with one review measuring a 94% PM2.5 improvement. The limitation is that the purifier itself does not provide PM2.5 readouts.
Pollen removal
Austin Air HealthMateNo score yet
Levoit P350-P
4.5
Pollen comments are fewer than pet and dust comments, but they are positive. Customers mention relief on pollen days and less pollen settling in a nursery.
Real-time air quality monitoring
Austin Air HealthMateNo score yet
Levoit P350-P
2.0
Real-time monitoring is absent, and reviewers clearly miss it. Buyers wanting live air-quality readings or automatic response should choose a smarter model.
Room temperature mixing
Austin Air HealthMateNo score yet
Levoit P350-P
4.0
A couple of users noticed a cooling or air-mixing effect from the upward airflow. This is a side benefit rather than a dedicated temperature feature.
Sleep mode
Austin Air HealthMateNo score yet
Levoit P350-P
4.5
Sleep mode is praised for quiet nighttime operation and dimmer lights. Several owners use it in bedrooms or move the unit there for sleep.
Performance
Display readability
Austin Air HealthMateNo score yet
Levoit P350-P
2.7
Indicator-ring expectations are mixed because this model lacks the richer display features found on other Levoit units. The comments point more to missing readouts than poor readability.
Filter availability
Austin Air HealthMateNo score yet
Levoit P350-P
4.5
Replacement filter availability is a plus for some buyers, especially because filters are easy to find on Amazon and arrive quickly. Availability was not a repeated problem.
Filter stages
Austin Air HealthMateNo score yet
Levoit P350-P
4.2
Experts describe a competent three-stage system built around a pre-filter, particle/HEPA stage, and carbon layer. The filtration stack is treated as the core reason the unit works well for pets.
True HEPA filter
Austin Air HealthMateNo score yet
Levoit P350-P
4.1
True HEPA messaging is mixed. One expert says Levoit no longer claims True HEPA on newer materials, while another still describes the filter as True HEPA and effective.
