No, a small portable air purifier cannot purify the air of an entire house, regardless of the size. Portable air purifiers only clean the air in a specific room or area where they are placed. You would need to purchase and run multiple portable air purifiers to match the coverage of a whole-house air purifier.
Air purifiers directly tackle the problem of indoor air polluted by a host of irritants, including dust mite allergen, mold spores, pollen, pet dander, VOCs, smoke, and other toxic fumes. Whole house air purifiers can address the issue of polluted indoor air on a whole-house as opposed to a room-by-room basis.
In a typical home environment, an effective air purifier can start to reduce these pollutants within 30 to 60 minutes. Noticeable improvements in air quality are often observed within a few hours, with significant reductions occurring over 24 hours of continuous use.
What are the downsides of air purifiers? There aren't a lot of downsides to having an air purifier in your home aside from the financial investment. Many ionizers, especially older models, can generate ozone when they are operating, which is known to exacerbate asthma.
Ozone-Generating Air Cleaners
One mechanism of damage results from ozone-olefin reactions, and another from ozone reacting with electron donors (such as glutathione). Inhalation of relatively small amounts of ozone can cause coughing, chest pain, throat irritation, and shortness of breath.
Ensure your air purifier has enough clearance around it to function optimally. Avoid placing it behind furniture or in tight corners where airflow might be restricted. Ideally, there should be at least 3-5 feet of clear space around the unit to allow for unimpeded air intake and output.
The takeaway? Air purifiers can make the air in your home cleaner and fresher, but they are not guaranteed to work for all odors and lingering smells.
Simple things you can do to improve your indoor air quality include: Reduce dust by vacuuming regularly and using a microfiber or damp cloth for dusting. Reduce humidity to avoid mold and mildew buildup and change appliance filters regularly. And make sure to test your home for dangerous gases like radon.
Many people think that switching it off during the night or when they're not present is a logical energy-saving measure, but it is recommended to keep it running constantly. Once you turn off your air purifier, the air quickly becomes contaminated again with mold, dust, dander, and other pollutants present in the air.
Whole-house air purifier costs range from $419 to $4,962, with an average of $2,610 depending on house size and filter type. Installing a whole-house air purifier costs $419 to $12,000, though most homeowners spend an average of $2,610.
Specialists recommend placing the device on the floor, because it is near the ground that there is a higher concentration of pollutants. Setting it on a shelf can significantly reduce the filtration efficiency.
A whole-house air purifier is undoubtedly worth the money for those with allergies, asthma, and other respiratory conditions. The system helps reduce symptoms by removing antagonistic air pollutants. This results in less frequent and intense allergy and/or asthma attacks.
When used correctly, air purifiers with HEPA filters can effectively reduce dust and other allergens in the air. They may be particularly useful if you're allergic to dust mites or pollen or if allergens trigger your asthma. You can choose from many types of air purifiers.
Bedroom. The most important room to put an air purifier in is the bedroom — yours as well as the bedrooms of your children.
Well, the answer isn't as easy. In a typical home, an effective air purifier starts to deliver clean air within 30 to 60 minutes. But this time changes, depending on several factors such as your room size, the indoor air quality and even the placement of the device.
Place your device at least 6 inches from walls, furniture, or other items while in use. Place your air purifier near the most likely source of indoor air pollution. Consider investing in an air purifier that shuts off automatically with a timer. Place your air purifier in a room where you spend most of your time.

HEPA filters capture 99.97% of particles as small as 0.3 microns and they are an effective instrument in filtering out mold, dust, pollen, and other air pollutants. This type of filter should be replaced every month or two to work efficiently.
Yes, air purifiers can help reduce dust in indoor environments. Air purifiers equipped with High-Efficiency Particulate Air (HEPA) filters are particularly effective at capturing airborne dust particles as small as 0.3 microns with 99.97% efficiency.
An air purifier helps remove odor-causing contaminants and restore your home to a fresh, clean smell. So, fire up an air purifier for farts, cooking odors, stinky pets, and anything else that leaves your home smelling unpleasant.
Room air cleaners are portable, electric appliances that remove fine particles, such as dust and pollen, from indoor air. A standard room air cleaner, operating continuously, uses approximately 450 kWh per year in electricity. This is more than the energy used by some new refrigerators!
However, in general, the duration of use required depends on the size of your space and the amount of indoor pollution (which varies throughout the year). This is why most manufacturers will recommend you to leave your air purifier running all day, especially if it comes equipped with an automatic setting.
In theory, you would get the best results by having an air purifier in every room of your home. However, the cost of doing this can make it impossible for most people. If you're wondering whether you need an air purifier for each room, start with an affordable two: one for your bedroom and one for the living area.
Mold is an obvious health risk in any home, but investing in an air purifier can help limit your exposure. The best among them will ideally offer HEPA-level filtration, with this level of filtration being able to trap up to 99.97% of airborne particles down to 0.3 microns in diameter.
