Levoit and Honeywell are two of the best-known names in home air purifiers, and many shoppers end up choosing between them. Both offer true HEPA models in a range of sizes, so the choice rarely comes down to brand alone. It comes down to the specific model: the room it is built for, how quiet it is, how its filters work and what they cost to replace.
This guide compares the two brands at the level you can rely on: typical product approach, features to check and how to decide for your room. Lineups change often, so we avoid model-by-model claims. We have not tested these products ourselves, so confirm specifications on each product page.
Levoit tends to appeal for
- A wide range of sizes
- Sleep modes and quieter low settings
- App-enabled options on some models
Honeywell tends to appeal for
- A long-established brand
- Simple, straightforward controls
- Models aimed at larger rooms
Key Takeaways
- Compare individual models on CADR, noise, filters and cost; brand alone does not decide.
- Both brands sell true HEPA units across a range of room sizes.
- Check each model’s manual for ionizer or similar modes and leave them off.
- Lineups change often, so confirm every spec on the current product page.
Allergies, Pets and Odors: What to Look For
For allergies, the true HEPA filter and correct sizing are the foundation, regardless of brand. For pets, look for a pre-filter that catches hair and is simple to clean, because hair is the first thing to clog the intake. For odors from pets, cooking or smoke, look for a substantial activated carbon layer and be prepared to replace it earlier than the HEPA, since carbon saturates sooner.
Both brands offer models with carbon layers, but the amount varies widely. If odors are a priority, read the specifications for the weight or thickness of the carbon, not just the word carbon. Pair the purifier with source control: regular cleaning, washing pet bedding, using a kitchen exhaust fan and keeping humidity in the 30 to 50 percent range.
Placement and Everyday Use
Wherever you buy, placement matters. Leave at least a foot of clear space on all sides, avoid corners and putting the unit behind furniture, and keep it on a hard, level surface. In a bedroom, a few feet from the bed works well. In a living room, place it near the seating area but not where it will be bumped.
Run it continuously on a low or medium setting rather than occasionally on high. Close windows and doors during pollen season or smoke events, and check the pre-filter monthly. Keep the manual and a note of the filter replacement date. These habits matter more than the logo on the unit, and they keep either brand working as designed.
Warranty, Support and Long-Term Ownership
Before you commit, read the warranty terms for the model you like. Note how long it lasts, what it covers (the motor, the electronics, the housing) and whether filters are excluded. Check how to make a claim and whether the maker has a record of responding. A longer warranty and clear support can matter more over several years than a small difference in features.
Think about availability of parts. Filters should be available for as long as you own the unit, and the maker should list the correct part numbers. If a model is discontinued, replacement filters may become harder to find, so buy a spare when you purchase if the model is older. Keep your order confirmation and the model number handy, and register the product if the maker offers it, so support can help you quickly if something goes wrong.
Finally, remember that the best unit is the one you will keep running. Choose for the room, the noise, the filters and the routine you can maintain, and confirm every specification on the current product page.
Air Purifiers to Compare
The table below lists purifiers from our affiliate partner. Compare smoke CADR, room size ratings and filter details across brands.
Features and Ozone
Some purifiers from various brands include ionizer or similar modes. The EPA advises against ozone-emitting air cleaners, so check the manual of any model you consider and prefer to leave such modes off. Mechanical filtration with a true HEPA filter is the approach we recommend regardless of brand.
App control, air quality sensors and auto mode are convenience features; decide if you will use them. They do not change filtration.
Levoit vs Honeywell at a Glance
The table below summarizes what to check.

How the Two Brands Position Their Products
Levoit has built a reputation with compact and mid-size towers for bedrooms and living rooms, often with a sleep mode, a filter indicator and, on some models, app control. Honeywell, a longstanding appliance brand, offers true HEPA purifiers across several sizes, including units intended for larger rooms, often with simpler controls and pre-filter designs.
These are general impressions, and both brands change their lineups. Treat them as a starting point, then compare the actual models you are considering on CADR, noise, filters and features.
What to Compare Model by Model
Start with the smoke CADR and the recommended room size, then compute your own target: about two-thirds of floor area at 8 foot ceilings. Compare the filter stack: a pre-filter, a true HEPA layer and, if odors matter, a carbon layer. Check how the pre-filter is cleaned and how often the main filter must be replaced.
Compare the noise at low and high, the display and light options and the controls. Check the replacement filter price and how widely available it is. Check the warranty.
Matching a Model to Your Room
The right comparison starts with your room, not the brand. Measure the floor area and ceiling height, then compute the smoke CADR you need: about two-thirds of the floor area at 8 foot ceilings, plus roughly 12 percent for each extra foot. For a 150 square foot bedroom that is about 100; for a 300 square foot living room, about 200.
Then list the models from each brand that meet your target. You will usually find several from each, and the differences between them are in noise, filter design, controls and cost. Choose the model that meets the CADR target at a fan speed you find comfortable, not the one with the biggest headline number.
Filters, Upkeep and Running Costs
The ongoing cost of any purifier is mostly its filters. Look at what each candidate model uses: whether the HEPA and carbon are combined in one cartridge or separate, how long the maker says each lasts, and what replacements cost. Check how easy they are to find from the manufacturer and from reliable retailers.
Washable pre-filters on some models reduce wear on the main filter. Look at how the filter indicator works: most count time rather than measure dirt, so plan to inspect the filter yourself. In a home with pets, smoke or construction dust, filters may need replacing sooner than the indicator suggests.
Noise, Light and Sleep
If the purifier will run in a bedroom, noise and light matter. Compare the manufacturer’s sound ratings at the lowest setting and at the speed you will actually use. Look for a sleep mode that dims or turns off the display. Remember that lab ratings are only a guide: the room, the surface under the unit and the distance from the bed all change what you hear.
Try the unit for the first few nights, adjust the placement and keep the receipt for the return window. If it is too noisy at the speed needed for your room, it may be undersized, and a larger model at a lower speed may be quieter.
Controls, Displays and Smart Features
Some models use simple knobs or buttons; others have touch panels, color displays and apps. Simple controls are easy for every member of the household, while apps and schedules appeal to people who like to automate. An auto mode with an air quality sensor can adjust the fan automatically, though sensors are approximate.
Whatever the brand, make sure you can operate the unit without an app and that it works if Wi-Fi is unavailable. Check whether the display can be dimmed or turned off for sleep.
How to Decide Between Them
If two models, one from each brand, meet your CADR target, compare them on noise at your working speed, replacement filter cost and availability, ease of cleaning and warranty. Pick the one that wins on the factors you care about most.
Do not worry about brand loyalty. A well-chosen, well-maintained unit from either maker will outperform a mismatched or neglected one. Confirm all details on the current product pages before you buy.
How to Choose
- Compare the specific model, not the brand.
- Size by smoke CADR, about two-thirds of floor area at 8 foot ceilings.
- Check the noise and the filter cost.
- Decide whether you want app control.
- Avoid ozone generating or ionizer modes; the EPA advises against ozone-emitting air cleaners.
Do
- Match the unit’s rated coverage to your room first
- Run it consistently, not only when the air feels bad
- Leave space around the unit for airflow
