air purifier at home

Air purifiers can be a helpful solution if you suffer from cat allergies but still want to share your home with a feline friend. Pet hair and dander can be unbearable for those with allergies. Cats that spend time outdoors can bring allergens, such as various pollens, back home with them. In addition, litter box odors and litter dust are often irritating to those with respiratory sensitivities. The benefits of an air purifier can extend to your cat if they also suffer from seasonal allergies.

Air purifiers remove harmful particles, along with dander and flying loose fur, from the air before they have a chance to settle on your clothes, furniture, or bedding. There are many types of air purifiers available, so we rounded up our favorites. Our list of reviews can help you get acquainted with the basics and see which one works for your household.

    Buyer’s Guide: Selecting The Best Air Purifier for Cat Allergies

    Choosing the best air purifier for your home can come down to several factors. There’s no universal air purifier that’s right for everyone. Look at the filter types, size, area cleaned, and replacement filter costs when comparing and choose the one that fits your needs. Here are a few things to consider when choosing the right one for you.

    What Do Air Purifiers Do?

    Air purifiers filter pollutants and allergens from the air. You don’t have to suffer from allergies or be a pet owner to reap the benefits of clean air in your home. However, using an air purifier can greatly reduce hair, dander, and odors caused by cats.

    If you are allergic to cats, an air purifier can be a helpful solution to breathing easier around your feline companion. It will reduce dander and hair in the air before those irritants can settle around you.

    Air purifiers can only capture these things as they float in the air. Once they’ve settled, they can’t be moved by the machine. Heavy allergens tend to settle quickly and can’t be removed in time.

    Room air purifiers can only work for a designated amount of space surrounding them. If you’d like multiple rooms to be filtered, moving the air purifier from room to room is necessary. You can also get multiple units for the rooms that you want to use them in.

    Getting the Most Out of Your Air Purifier

    Consider the rooms in which you want to use an air purifier. Bedrooms and living rooms seem to be the most common choices because people spend most of their time in these areas. Place the purifier away from walls and curtains. Nothing should obstruct the airflow on all sides of the machine. Using the air purifier where you need it most will help you receive the maximum benefits.

    Keep it running for the cleanest air possible. Turning it off will let allergens and particles settle. Keep the windows and doors to the outside closed near the air purifier when it’s running. If your machine has a timer feature, you can only use the machine when you want to, saving energy.

    Clean your filters. An air purifier is only as good as its filters. They must be replaced over time. Usually, that period is approximately every 6 months. Carbon filters that capture and neutralize odors in the air should be replaced every 3 months. If your unit comes with permanent filters, learn how to clean them. Some require vacuuming. Others require cleaning with water and then allowing them to fully dry. Keeping your filters clean will not only keep your air cleaner but will also extend the life of your air purifier.

    Improving the Air Quality in Your Home

    In addition to the air purifier, you can do things to help improve your home’s air quality. The air purifier can only do so much. You can help reduce its workload by doing the following.

    Limit the number of chemicals that you use inside. Paints, pesticides, cleaners, and glue can all lead to poor air quality in your home. While your air purifier will help, it won’t eliminate them from the air if they’re used regularly.

    Reduce or stop smoking indoors, and limit how often you burn candles in your home.

    Open your windows on pleasant days to let in clean air. If you suffer from allergies, use an air conditioner with an air filter. This will help cycle the air in your home.

    If your home has exhaust fans, use them regularly.

    Most of all, vacuum. By cleaning your floors, furniture, and surfaces in your homes, you can gather up the particles missed by the air purifier. When these particles are stirred up into the air again, whatever you miss has another shot at being grabbed by the machine.

    Types of Air Purifier Filters

    Many air purifiers have more than one filter. The pre-filter is used to grab large particles, like cat hair, in the air as they pass through it. The main filter is used to capture smaller particles and allergens. Activated charcoal or carbon filters work for odor control. Some units include all three filters, and some only have the first two.

    HEPA filters are high-efficiency particulate air filters and are recommended by the American Lung Association. Your main filter should be a HEPA filter. It captures 99.97% of particles that are 0.3 millionths of a meter or larger.

    Activated charcoal or carbon filters work against odors. Your air purifier can remove particles from the air. However, without a filter for odor control, it won’t do much against smells. These filters can trap gases and fumes, cooking odors, and litter box odors. By placing the air purifier in the same room as the litter box, you can help eliminate odors even further.

    Are Air Purifiers Noisy?

    The air purifiers work by pulling air in through the filtration system and circulating it back out once it’s cleaned. Internal fans usually make this happen. While some of them can produce a humming sound, others are virtually silent.

    When considering where you want to use your unit, choosing one that operates quietly, even at high speeds, will be better for areas like offices and bedrooms. Some machines offer a silent option that must be selected when you want a quieter clean.

    Air Purifier Features

    Air purifiers can come with additional features. This may affect the price of the unit. Some of these features can make operating the machine more convenient, and others you may not find to be necessary.

    Filter-Replacement Indicator Light

    A light will appear on the panel of the machine letting you know that your filter is close to the time that it needs to be replaced or that it’s now the time that it must be replaced. If you can remember to replace your filter according to how often you use your machine, this feature may not be needed. It can be convenient when you forget to do it, though. Keeping your filters clean will keep your machine running smoothly, so replacing them on time is essential.

    Dimming LED Panel

    If your machine lights up and you’re using it in a bedroom, being able to adjust the brightness of the display is helpful. If you’re using the machine in a living or common room, how bright it is may not matter overnight.

    Setting your machine to operate for a certain amount of time every day can be useful when you don’t want to turn it on and off manually. However, if you’re using a portable air purifier that sits on your desk or nightstand, turning it on and off might be so easy that a timer is unnecessary.

    Remote Control

    It’s convenient to be able to adjust your air purifier from across the room. Depending on how often you want to change the settings, the remote control could be a helpful feature.

    Smart Controls

    Some air purifiers can be controlled by your phone or a voice command. While these features may be more expensive, they don’t contribute to the unit’s overall performance. These are specific features that appeal to the user’s convenience. Having Smart capabilities does not mean that the unit will work better than one that doesn’t have them.
