HELPFUL HINTS
Living with pets brings lots of joy, but it can also make the air in your home harder to keep clean. If you share your space with a cat or dog, you know the feeling of walking through the front door to that familiar pet-home scent and spotting fur drifting across the floor right after you've cleaned.
No matter how often you vacuum or open the windows, a pet home is in a constant struggle with fur, dander, odors, and other airborne troublemakers. They make fresh, clean air more of a challenge in pet homes.
In this article, we dive into the importance of pet air purifiers, what to look for in an air purifier for pets, and the helpful features of LG's pet-focused air purifiers.

Ever feel like the pet fur is always one step ahead of you? Or wonder why that familiar "pet smell" lingers even with the windows wide open?
That's because a pet home deals with more than ordinary dust. Fur, dander, allergens, and odors are all being created at once, all the time. That's why you need a different game plan for keeping the air clean.
Pets release fur and dander constantly, even outside shedding season. Beyond the visible fur, microscopic dander and pet-derived allergens1) can also drift through your living space, making consistent air care important.
• Pet fur and dander can carry pet-derived allergens.
• They build up easily on sofas, curtains, bedding, and other surfaces around the home.
• Even after settling, they can become airborne again with everyday movement or normal airflow.
Cooking smells fade on their own or clear out when you open a window. Pet odors don't. They come from many sources at once, including skin oils, saliva, ammonia in urine, and volatile compounds released from litter boxes and other pet messes. That's why they usually call for a different approach than everyday household smells.
When pet odors linger, many people turn to air fresheners or deodorizing sprays. They can make your home smell fresher for a while, but in many cases, they simply cover up odors instead of removing what's causing them. Some scented products may also release chemicals into the air that can be irritating to both people and pets.
Even if the air seems fine to you, the same may not be true for everyone in your home. Pet-derived allergens are often invisible and can build up indoors over time. For someone with pet allergies, that can mean sneezing, watery eyes, or a stuffy nose. If your household includes young children, older adults, people with respiratory conditions, or frequent visitors, managing allergens day to day can make your home more comfortable for everyone.
In a home with pets, fur, dander, allergens, and odors are produced continuously, as part of everyday life. Each behaves differently, but they all affect your indoor air at the same time, which is why a pet home needs steadier air care than others. So rather than managing fine dust alone, it helps to choose an air purifier that can handle fur, odors, and allergens together.
Pets playing indoors with airborne pet hair, dander, odors, and dust
| Category | Home without Pets | Home with Pets |
| Hair & Dander | From everydoay activity and seasonal shedding | Produced daily, as a costant part of life |
| Allergens | Mostly ordinary household dust | Pet-derived allergrens |
| Odor | From cooking and daily life; clears after airing out | Form many sources at once; continuously renewed |
| Indoor Air Quality | Shaped largely by ventilation and outdoor air | Changes continuously with pets' daily activity |
When you're choosing an air purifier, it helps to know that they're not all designed with the same priorities. Some focus mainly on the fine dust common in most homes, while others are made with pet households in mind, handling pet hair, dander, and odors too. That's why it pays to look past basic purifying performance and check for features designed for pet homes.
Most of what pets leave in your air, you'll never see. Microscopic dander, pet-derived allergens, and lingering odors can continue to build up in your home, even after you've cleaned.
Because these pollutants behave differently, it's worth choosing an air purifier with a filtration system built to handle all of them. Here are the key features to look for.
✓ H13 HEPA Filter
If you're concerned about pet dander, pet-derived allergens, or fine particles such as PM2.5, start with an air purifier with an H13 HEPA Filter. It helps capture tiny airborne particles that are difficult to see, helping keep your indoor air cleaner.
✓ Photocatalytic Deodorization Filter2)
Pet odors can linger long after the source is gone. A Photocatalytic Deodorization Filter helps continuously break down odor-causing substances, including ammonia and acetic acid from pet messes and other everyday pet odors. Compared with conventional deodorizing filters, it helps maintain deodorizing performance for longer.
One advantage of this filter is that you can refresh it yourself using light. When deodorizing performance begins to decline, placing the filter under fluorescent light or direct sunlight for about three hours helps reactivate the photocatalytic coating and maintain its performance.
✓ Easy-to-clean Pre-Filter
Pet hair is one of the first things an air purifier has to deal with. The Pre-Filter captures these larger particles before they reach the main filter, helping keep the filtration system working efficiently.
The standard Easy-to-Clean Pre-Filter can be easily taken out, washed with water, and reused, making routine maintenance simple. Keeping the Pre-Filter clean also helps your purifier perform consistently over time.
In a pet home, pollutants are produced around the clock, so the air purifier often runs for long stretches. That makes it worth checking not just for strong cleaning performance, but for features that make all-day use comfortable.
✓ Sleep Mode: Runs quietly at night, keeping the room comfortable for both you and your pet.
✓ Auto Mode: Automatically adjusts the fan speed to match changes in indoor air quality and your pet's activity.
Managing all of that fur, dander, odors, and allergens is exactly what LG PuriCare™ pet care air purifiers are built for. Beyond those core features, they add dedicated functions designed specifically for life with a pet.
As your pet moves around and the air changes, LG pet care air purifiers detect those shifts and respond, managing the air more effectively moment to moment. They include:
• Pet Mode: Directs airflow toward the floor to capture more pet hair floating near ground level.
• PM1.0 Sensor3): Detects ultrafine particles in real time to monitor changes in indoor air quality with greater precision.
From filter upkeep to product status, these smart features make it easier to keep your purifier running as it should.
• Filter Replacement Alert: Tells you when it's time to change the filter, helping maintain performance.
• LG ThinQ™ App Notifications: Monitor indoor air quality, check product status, and control your air purifier remotely through the app.
LG offers a range of air purifiers for pets designed for different types of pets and living situations. Because each model offers different features based on room size and household needs, the right choice depends on the features that matter most to your household.
Here's a walkthrough of LG's pet care lineup. Compare where each model shines to find the right one for your home.

Life with pets is a joy, but the air they share with you calls for a little extra care. Choosing an air purifier that helps manage pet hair, dander, odors, and allergens can help both you and your pets live more cleanly and comfortably. Explore LG's air purifier for pets lineup to find the air care solution that fits your home.
Air purifiers are often most effective when placed where pets spend the most time and where airflow is not blocked by furniture or walls.
An air purifier can help reduce and manage pet odors, but no air purifier can completely eliminate every odor on its own. Because pet odors come from multiple sources, such as skin oils, saliva, urine, and litter boxes, a Photocatalytic Deodorization Filter or other deodorization filter can help manage odor-causing substances more effectively. Regular cleaning of your home and your pet's living area also helps maintain fresher indoor air.
Households with multiple pets may experience higher levels of pet-related particles and odors. Choosing a model with suitable coverage and filtration features may help support indoor air management.
