Air purifiers effectively capture and eliminate many common respiratory pathogens including influenza viruses, rhinoviruses (common cold), coronaviruses, streptococcus bacteria, staphylococcus bacteria, and various fungal spores. Airdog's TPA® technology is particularly effective against viruses because it captures particles as small as 0.0146 microns, which includes virtually all respiratory viruses that typically range from 0.02-0.3 microns. Unlike HEPA filters that simply trap pathogens, TPA® technology destroys microorganisms on contact, preventing them from potentially growing or being re-released.

While air purifiers cannot guarantee complete protection against all illnesses, they significantly reduce airborne pathogen concentrations and can substantially lower transmission risk when combined with other preventive measures like hand washing and surface cleaning. Studies have shown that effective air filtration can reduce respiratory infection rates in households and healthcare settings. The key is continuous operation and proper sizing for your space—air purifiers work best as part of a comprehensive approach to infection prevention.

Yes, air purifiers are particularly valuable when household members are ill because they help prevent the spread to other family members by continuously removing infectious particles from the air. Running air purifiers in the sick person's room and common areas can significantly reduce the concentration of airborne pathogens that could infect others. This is especially important for protecting vulnerable family members like elderly relatives, young children, or anyone with compromised immune systems who are at higher risk for severe complications. Hospitals often use air purifiers to help protect staff members and other hospital patients and visitors from airborne viruses and bacteria.

Air purifiers that capture bacteria can help reduce exposure to antibiotic-resistant strains like MRSA, though the antibiotic resistance itself doesn't affect how well physical filtration works. Airdog's TPA® technology actually destroys bacteria and kills viruses on contact rather than just trapping them, which is particularly beneficial for antibiotic-resistant organisms since it eliminates them entirely rather than potentially allowing them to survive in filter media. However, air purifiers should be viewed as one component of infection control rather than a complete solution for managing resistant organisms.

Absolutely. Continuous operation during high-risk periods provides the best protection because viruses and bacteria are constantly being introduced into your air through breathing, talking, and activities of daily living. Pathogens can remain viable in air for hours, so intermittent operation leaves gaps where infectious particles can accumulate and spread. Many families find that running air purifiers continuously during cold and flu season results in fewer illnesses and faster recovery times when someone does get sick.

No, air purifiers should complement, not replace, other important infection prevention practices like hand washing, surface disinfection, vaccination, and staying home when sick. However, they address the often-overlooked airborne transmission route that other methods cannot tackle. The most effective approach combines clean air with good hygiene practices and appropriate medical care when needed.

Air purifiers begin capturing pathogens immediately upon startup, with noticeable air quality improvements typically occurring within 15-30 minutes in properly sized rooms. However, it can take several air changes (usually 1-3 hours depending on room size and purifier capacity) to significantly reduce overall pathogen concentrations. For maximum effectiveness against illness transmission, it's best to run air purifiers continuously rather than only during obvious exposure events.

UV-C light systems neutralize pathogens including by disrupting their DNA or RNA and preventing them from reproducing. While this technology can be effective, some purifiers that use UV light or ionizers can create ozone, a harmful gas to our body especially our lungs and respiratory system. 

Airdog air purifiers offer an alternative to UV-C purification systems.  Germicidal UV light kills airborne viruses and most bacteria. Airdog uses a patented TPA (Two-Pole Active) technology to capture airborne contaminants, including bacteria, viruses, dust, allergens, and fine particles. 

If you are concerned about ozone exposure, it's important to choose an air purifier with low ozone emissions.

High-quality air purifiers like Airdog units that don't produce ozone are very safe for continuous use around family members of all ages. Ozone is a respiratory irritant that can trigger asthma attacks.  The US EPA advises against using ozone generating products. Unlike some purifiers that use UV lights or ionizers that can create harmful byproducts, TPA® technology safely destroys pathogens without releasing any dangerous chemicals into your air. The main consideration is ensuring proper maintenance and cleaning of washable filters to prevent any potential bacterial growth, though this is much less of a concern than with disposable filters that can harbor pathogens if not changed frequently enough.

When researching air purifiers with activated carbon or replaceable filters you should consider what you are trying to remove, what your budget is, and how much maintenance you are willing to perform. Activated carbon filters improve indoor air quality by absorbing odors and volatile organic compounds (VOCs). They are less effective at capturing airborne particles such as dust, pollen, and allergens. 

Traditional HEPA air purifiers use high-efficiency particulate air HEPA filters to trap microscopic particles. True HEPA filtration is backed by science for air purification. The CDC also recommends HEPA filtration as a strategy for reducing airborne particles that may carry viruses. 

Traditional HEPA filters require frequent replacement, which can lead to recurring expenses and additional plastic waste over the course of time. Airdog air purifiers offer an alternative with washable filters to reduce recurring replacement costs . Unlike conventional HEPA models, Airdog uses Two-Pole Active (TPA) technology to capture and destroy airborne particles at their source without disposable HEPA filters.

When comparing models on the market, consider filtration efficacy, clean air delivery rate (CADR), maintenance costs, and the specific contaminants you want to address. If odors and VOCs are your primary concern, activated carbon filtration may be beneficial. However, if you're looking for effective particle removal with lower recurring maintenance costs, Airdog's washable filtration technology is worth considering.

Clean Air Delivery Rate (CADR) measures air changes per hour. Higher CADR ensures rapid air changes per hour. CADR is typically expressed in cubic feet per minute (CFM), CADR is an important indicator of an air purifier's performance. 

For small rooms, an air purifier with a lower CADR may provide sufficient filtration, while larger spaces require a higher CADR to maintain effective air circulation. Room dimensions, including length, width, and ceiling height in feet or inches, help determine the appropriate CADR. Note that CADR measures clean air delivery rather than the physical diameter of the purifier or its filters.

Airdog air purifiers offer impressive air purification performance, combining effective particle removal with washable, reusable filtration technology. 

Air purifier sensors monitor indoor air quality by detecting airborne pollutants, such as dust, smoke, and fine particulate matter. These sensors provide real-time information about pollution levels, helping air purifiers operate more efficiently. Air purifiers with built-in particle sensors, like Airdog's, automatically adjust fan speeds when air contamination is high. This increases filtration when needed and reducing fan speed as air quality improves.

For instance, when sickness is in the air, an Airdog air purifier with automatic mode can detect the increase in particulate pollution and boost its fan speed to help clean the air faster. This smart technology helps maintain healthier indoor air quality while minimizing unnecessary energy consumption and noise.

For optimal performance, place your air purifier in a central, open location where air can circulate freely. Position it near common sources of indoor air pollution, such as areas where dust accumulates, but avoid placing it directly against walls, furniture, or other obstacles that could block airflow. As a general starting point, maintain a distance of at least 12–24 inches from surrounding objects, or follow the manufacturer's recommended clearance.

Keep your air purifier away from open windows and doors when outdoor pollution levels are high, as incoming contaminants can make filtration less effective. Air purifiers work best in combination with proper ventilation, which helps remove indoor pollutants and introduce fresh air. 

For the best results, place your air purifier in rooms where you spend the most time, such as bedrooms, living rooms, or home offices. Airdog air purifiers use advanced filtration technology designed to capture airborne particles, making them a practical choice for maintaining cleaner indoor air. The key point is to choose a location that allows unrestricted airflow and supports effective air circulation throughout the room. While air filtration is a proven way to reduce airborne particles, proper placement helps maximize your purifier's performance.
