It’s undeniable that current pollution significantly impacts our quality of life. Due to these challenges we face, air purifier products have become increasingly popular in recent years, leading many to wonder: How necessary are air purifiers, and how effective are they? This article will address common questions about air purifiers that everyone should know.
1. If I already have an air conditioner, do I still need an air purifier?
Yes. Air conditioners and air purifiers serve different purposes.
An air conditioner circulates and cools the air but does not filter out dust or germs.
An air purifier, however, removes pollutants and provides clean, breathable air.
In short — air conditioner = temperature control, air purifier = clean air.
2. Can an air purifier eliminate viruses?
It depends on the filter technology.
Regular HEPA filters only trap viruses but don’t destroy them.
Airdog’s TPA Technology actively kills up to 99.99% of over 400 virus strains — offering true protection.
3. Can the air purifier filter be washed?
The answer to this question depends on the filter characteristics as well. HEPA filters are made of paper, which naturally cannot be washed or cleaned—they must be replaced only. This becomes a costly expense in the long run. Meanwhile, air purifiers with TPA Technology are designed to solve this pain point, with features that allow each filter layer to be removed for cleaning and reused throughout the product’s lifespan. There’s no need to keep buying replacement filters, resulting in long-term maintenance cost savings.
4. Can I use an air purifier and a fan together?
Running an air purifier together with a fan is possible, but caution is needed. Fans may blow dust particles around the room, preventing the air purifier from effectively drawing in and filtering the air completely. If you do use both, you should keep doors and windows tightly closed so the air purifier can fully filter only the indoor air for maximum cleanliness.
5. How much electricity does an air purifier use if it runs all day?
Actually, air purifiers consume very little power.
You can calculate it using this formula:
Wattage × Number of units ÷ 1,000 × Hours used = kWh per day
Example:
If your air purifier uses 27 watts and runs 24 hours a day
→ (27 ÷ 1,000) × 24 = 0.468 kWh/day
If electricity costs 5 THB per unit
→ 0.468 × 5 = 2.35 THB/day
That’s only about 70 THB per month.
