A levoit pet air purifier can cut down pet dander, fur and odors in the rooms where your animals spend the most time. This guide walks you through matching a Levoit model to your room size, understanding the filter stack, placing the unit for best airflow, and keeping it running well so it does its job between filter changes.

Why Levoit Models Suit Many Pet Households

Levoit makes a range of tower and tabletop air purifiers, and several of them are marketed specifically to pet owners. Their pet-focused models typically pair a HEPA filter with a activated carbon layer and a pre-filter that catches larger hair before it reaches the finer media. For households with dogs or cats, that combination addresses the three main complaints: airborne dander, shedding fur and litter or food odors. Manufacturers specify that HEPA filters capture at least 99.97% of particles at 0.3 microns, which covers much of the allergen size range, though no purifier removes every particle from a room.

Owners often report that the biggest difference comes from running the unit consistently rather than only when guests arrive. If you are new to this category, our overview of Best Air Purifier Pets: 7 Picks and What Actually Matters (2026) explains what features matter most before you narrow down a model.

Step 1: Measure Your Room and Match the Model

Room size is the first filter for any purifier decision. Manufacturers rate their units with a Clean Air Delivery Rate (CADR), which estimates how many cubic feet of filtered air the unit delivers per minute for smoke, pollen and dust. A common rule of thumb is to choose a unit whose CADR for smoke is at least two-thirds of the room area in square feet, though many pet owners go higher because dander and fur are produced constantly.

  1. Measure the length and width of the room in feet and multiply them to get square footage.
  2. Multiply the room’s square footage by the number of ceiling feet, or use a rough room volume figure in cubic feet.
  3. Check the CADR listed on the unit for the room you plan to use it in.
  4. If you have more than one pet, or a shedding breed, aim for the upper end of the recommended room size.

Step 2: Understand the Filter Stack

Most pet-oriented Levoit units use a multi-stage filter. Knowing what each layer does helps you judge performance and plan replacements.

Filter layer What it catches What to check
Pre-filter Large hair, fur clumps, lint Rinse or vacuum regularly; often washable
True HEPA Fine dander, pollen, dust, pet allergens Replace on the manufacturer’s schedule; do not wash
Activated carbon Odors from litter, food and bedding Odor control weakens as the carbon saturates

Check whether your model uses a true HEPA filter or a “HEPA-type” filter. The term “true HEPA” is the one that carries a defined efficiency standard, so read the spec sheet carefully before you buy.

Step 3: Place the Purifier for Maximum Airflow

Placement determines how much air actually passes through the filter. A purifier tucked into a corner or shoved behind furniture can lose a large share of its effectiveness.

  • Leave at least 6 to 12 inches of clearance on all sides, or as the manual specifies.
  • Keep it away from walls and curtains so the intake is not blocked.
  • Position it where pets rest, such as near a dog bed or cat tree, but not where they can knock it over or chew the cord.
  • Avoid placing it directly in the path of a heater or air conditioner vent, which can disturb airflow patterns.
  • In multi-room homes, run the unit with doors open or move it between rooms on a schedule.

Step 4: Set Up the Controls and Auto Mode

Most Levoit units include a fan speed setting, a sleep mode and an auto mode that adjusts fan speed based on sensed particle levels. For pet homes, auto mode is usually the most practical choice because dander levels rise after play, grooming or feeding and drop again afterward. Run the unit on a low or sleep setting overnight, and on a higher setting during the day or after vacuuming.

If your model has an indicator light, learn what the colors mean before you start troubleshooting. Our guide to Levoit Air Purifier Red Light: What It Means and How to Fix It walks through the common causes.

Step 5: Replace Filters on Schedule

A filter that is past its useful life stops capturing particles efficiently and can release trapped material back into the room. Manufacturers typically give a replacement interval based on hours of use or air quality readings, and many Levoit models include a filter life indicator. Pet homes tend to load filters faster, so check the pre-filter more often than the manual suggests.

  1. Turn the unit off and unplug it.
  2. Remove the outer cover and pull out the pre-filter. Vacuum or rinse it, and let it dry fully if it is washable.
  3. Remove the HEPA and carbon filters. Do not wash the HEPA filter.
  4. Install the replacement filters in the order shown in the manual, with the correct airflow direction.
  5. Reset the filter indicator, then plug the unit back in.

Common Mistakes Pet Owners Make

  • Buying for the box size, not the room. A compact unit in a large living room will run constantly and still struggle.
  • Ignoring the pre-filter. A clogged pre-filter reduces airflow and shortens the life of the HEPA layer.
  • Washing the HEPA filter. Water damages the fiber media and reduces capture efficiency.
  • Turning the unit off when you leave. Dander settles back onto surfaces quickly; running the unit while you are out keeps levels lower when you return.
  • Expecting a purifier to replace cleaning. Vacuuming with a HEPA vacuum, washing pet bedding and brushing animals outdoors all reduce the load the purifier must handle.

Tips for Better Results

  • Brush pets outdoors or in a bathroom with the door closed to keep fur out of the main living area.
  • Wash pet bedding weekly in hot water if the manufacturer allows it.
  • Keep a second unit in a bedroom if a pet sleeps there or if anyone in the home has allergies.
  • Track filter changes on a calendar or phone reminder so the schedule does not depend on memory.

FAQ

Is a levoit pet air purifier good for dog and cat hair?

Yes, a Levoit model with a pre-filter and HEPA layer can capture much of the loose hair and fine dander that floats in the air. It will not stop hair from settling on furniture, so regular vacuuming and brushing are still needed.

How do I know which Levoit model is right for my room?

Compare the room’s square footage with the CADR and recommended room size listed for each model. If you have multiple pets or a heavy shedder, choose a unit rated for a larger room than you actually have.

Should I run the purifier all day?

Running it continuously on a low or auto setting is the most effective approach for pet homes. Dander builds up constantly, so intermittent use leaves gaps in coverage.

Can I wash the HEPA filter?

No. Manufacturers specify that true HEPA filters should not be washed, because water damages the fibers. Only wash the pre-filter if the manual says it is washable.

How often should I replace the filters?

Follow the replacement interval in your manual or the filter indicator on the unit. Pet homes often need more frequent pre-filter cleaning and may reach HEPA replacement sooner than the baseline schedule.

Will a levoit pet air purifier remove pet odors?

Models with an activated carbon layer can reduce many common odors from litter boxes, food and bedding. The carbon eventually saturates, so odor control weakens over time and the carbon layer needs replacing.

Does a purifier help with pet allergies?

It can reduce airborne allergens in the room, which may ease symptoms for some people. It does not replace medical treatment, so anyone with significant allergies or asthma should consult an allergist or doctor about a full management plan.

Conclusion

A levoit pet air purifier works best when the model matches your room size, the filter stack suits your pets’ shedding and odor levels, and the unit is placed where air can move freely. Set it to auto or run it continuously, change the pre-filter often, and replace the HEPA and carbon filters on schedule. Combined with regular brushing and cleaning, that routine keeps the air in your pet spaces noticeably fresher.
