Frequently Asked Questions
Everything you need to know about cleaner indoor air, choosing the right purifier, filter care, delivery, warranty, and getting the best from your product.
What is an air purifier, and how does it work?
An air purifier is a device that draws in indoor air, passes it through a filtration system to capture airborne pollutants, and circulates filtered air back into the room. Depending on the model, air purifiers may use True HEPA filters, activated carbon filters, and additional air-cleaning technologies.
Why do I need an air purifier if I already clean my house regularly?
Regular cleaning removes visible dust and dirt from surfaces, but fine airborne particles can remain suspended in indoor air. An air purifier helps capture dust, pollen, pet dander, and other airborne particles that routine cleaning may not remove. Using an air purifier alongside regular household cleaning can help maintain cleaner indoor air.
What pollutants can an air purifier remove from indoor air?
Air purifiers equipped with effective filtration systems can help capture airborne dust, pollen, pet dander, smoke particles, and fine particulate matter. Models with activated carbon filters can also help reduce certain household odours and gases. Actual performance depends on the filtration system and indoor conditions.
Can an air purifier help reduce PM2.5 and PM10 pollution?
Yes. Air purifiers with effective particle filtration can help reduce airborne PM2.5 and PM10 pollution indoors. PM2.5 refers to particles measuring 2.5 micrometres or smaller, while PM10 refers to particles measuring 10 micrometres or smaller.
WINIX air purifiers equipped with True HEPA filtration can help capture fine airborne particles, including PM2.5 and PM10, supporting cleaner indoor air. Selected models also feature PlasmaWave® technology, which complements the filtration system for enhanced air purification. Actual performance depends on room size, airflow, and operating conditions.
Can an air purifier help with allergies, dust, and pet dander?
Yes. Air purifiers equipped with True HEPA filtration can help capture airborne allergens such as pollen, pet dander, dust, and dust-mite particles.
However, air purifiers do not cure allergies or eliminate every allergen from indoor environments. Regular cleaning of bedding, furniture, and floors remains important.
Can an air purifier remove cooking smells, pet odours, and smoke?
Air purifiers with activated carbon filtration can help reduce certain household odours caused by cooking, pets, and smoke. Particle filters can also help capture airborne smoke particles.
Effectiveness depends on the type and amount of activated carbon, the pollution source, room conditions, and ventilation.
How do I choose the best air purifier for my home?
Consider your room size, Clean Air Delivery Rate (CADR), filtration technology, noise level, energy consumption, and replacement-filter costs. Choose an air purifier with verified room coverage and filtration performance that matches your needs.
WINIX offers a range of air purifiers featuring True HEPA filtration, activated carbon filters, and PlasmaWave® technology in selected models, helping maintain cleaner indoor air. To find a suitable model, use the WINIX Find My Fit for personalized air purifier recommendations based on your needs and preferred features.
Which air purifier is suitable for my bedroom or living room?
The right air purifier depends on your room size, ceiling height, indoor pollution levels, and preferred features. Smaller rooms generally require compact, quiet air purifiers, while larger living spaces benefit from higher Clean Air Delivery Rates (CADR) and greater airflow.
WINIX offers the Mini 360 and A231 for smaller bedrooms and personal spaces, the T500 for bedrooms and medium-sized rooms, and the T800 for larger living rooms. These models offer effective particle filtration, with PlasmaWave® technology available on selected models. To find the most suitable option, explore the WINIX Find My Fit tool for recommendations based on your requirements.
What is CADR, and why is it important?
CADR stands for Clean Air Delivery Rate. It measures the volume of filtered air an air purifier delivers per unit of time, usually expressed in cubic metres per hour (m³/h). A higher CADR generally indicates faster airborne particle removal under comparable testing conditions, helping customers choose an air purifier suitable for their room size.
The WINIX T800 Air Purifier offers a published CADR of 500 m³/h, making it an option for larger living spaces. WINIX also offers other models for different room sizes and air-cleaning requirements. Customers can compare product specifications or use the WINIX Find My Fit tool to select a suitable air purifier.
Can one air purifier clean the air in multiple rooms?
An air purifier is generally most effective in the room where it is placed. Walls, closed doors, and limited airflow between rooms can reduce its effectiveness in other areas.
For separate rooms, using an appropriately sized air purifier in each room may provide more consistent filtration.
What is the difference between an air purifier and an air conditioner?
An air conditioner primarily controls indoor temperature, while an air purifier is designed to reduce airborne pollutants through filtration. Both devices can be used together, but an air purifier does not replace cooling or appropriate ventilation.
What is PlasmaWave® technology, and how does it work?
PlasmaWave® is an air-cleaning technology developed by WINIX that generates positive and negative ions as part of its electronic air-treatment process.
It is designed to complement the purifier's filtration system. WINIX models combine PlasmaWave® with True HEPA and activated carbon filtration as part of a multi-stage air-cleaning system.
What are the benefits of PlasmaWave® technology?
PlasmaWave® technology provides an additional electronic air-treatment process alongside the purifier's physical filtration system.
It is designed to complement True HEPA and activated carbon filtration, which help capture airborne particles and reduce certain household odours. Specific performance claims depend on verified testing.
How is PlasmaWave® technology different from True HEPA filtration?
True HEPA filtration mechanically captures airborne particles such as dust, pollen, and pet dander. PlasmaWave® is an electronic air-treatment technology that complements physical filters rather than replacing them. Together, these technologies perform different air-cleaning functions in compatible WINIX air purifiers.
Does PlasmaWave® technology produce ozone?
PlasmaWave® uses an electronic air-treatment process. Ozone emission levels and relevant safety certifications should be checked against the official testing documentation for the specific model. Customers can refer to the relevant WINIX product specifications or contact WINIX India for verified certification information.
Can PlasmaWave® technology be turned on or off?
Yes. WINIX air purifiers equipped with user-controllable PlasmaWave® technology allow users to easily switch the feature on or off according to their preferences. This provides flexibility while the air purifier continues operating its filtration system. Refer to the product manual for specific control instructions.
Does PlasmaWave® technology require maintenance or replacement?
No. WINIX PlasmaWave® technology does not require regular maintenance or periodic replacement, as it is a built-in electronic air-treatment technology rather than a replaceable filter.
However, the air purifier's physical filters require separate maintenance and replacement according to the manufacturer's guidelines to maintain effective air purification performance.
What is the difference between a True HEPA filter and an activated carbon filter?
A True HEPA filter captures fine airborne particles such as dust, pollen, and pet dander.
An activated carbon filter helps adsorb certain gases and household odours.
These filtration technologies serve different purposes and are often combined to address multiple types of indoor air pollutants.
What is Auto Mode, and how does it work?
Auto Mode uses built-in air-quality sensors to automatically adjust the purifier's fan speed according to detected air conditions.
Selected WINIX air purifiers feature Auto Mode, helping reduce the need for frequent manual adjustments. Sensor capabilities vary by model.
Can I use an air purifier while sleeping?
Yes. Air purifiers can operate during sleep when used according to the manufacturer's instructions.
Models with Sleep Mode or quiet fan settings help reduce operating noise during nighttime use. Actual noise levels vary by model and fan speed.
How many hours a day should I run my air purifier?
Air purifiers can be operated for extended periods or continuously when permitted by the manufacturer's instructions.
Continuous operation can help maintain lower airborne particle levels, particularly when indoor pollution sources are ongoing. Auto Mode, where available, can adjust fan speed according to detected air conditions.
Should I keep doors and windows closed while using an air purifier?
Keeping doors and windows closed when practical can help reduce the entry of outdoor particulate pollution and improve filtration effectiveness.
However, appropriate ventilation remains important, especially when indoor gases or other pollutants are present.
Where should I place an air purifier for the best performance?
Place the air purifier on a stable surface with adequate clearance around its air intake and outlet.
Avoid positioning it behind furniture, curtains, or other objects that block airflow. Follow the manufacturer's placement instructions for the specific model.
How often should I replace my air purifier filters?
Filter replacement frequency depends on the model, filter type, daily usage, and indoor pollution levels.
Follow the recommended replacement schedule in the product manual and check the filter replacement indicator, where available.
Can I wash or vacuum-clean air purifier filters?
Filter cleaning requirements depend on the filter type and manufacturer's instructions.
Certain pre-filters can be cleaned using a vacuum cleaner. True HEPA and activated carbon replacement filters should not be washed with water unless the manufacturer explicitly permits it.
Follow the model-specific maintenance instructions and replace filters at the recommended intervals.
Does an air purifier consume a lot of electricity?
Electricity consumption depends on the purifier's power rating, fan speed, and operating hours.
