I have used many air purifiers n humidifiers in the past 25 years.
Panasonic, sharp, Samsung, Toshiba n many others.
The problems I face with all these... Not long lasting, and filter replacement got more expensive n hard to come by or discontinued as time goes by.
Electricity bill might go up as the filters get clogged when used, smelly too.
Eventhough with new filters, it sometimes smell still due to static dusts stuck to the motors or fins inside (usually cannot be cleaned at all). If spoilt, need to buy anew.
Usage Shelf life, usually 2 to 3 years.
Humidifiers bought uses ultrasonic. These mists are not gud in bedroom. It can cause molds on certain books or furniture in long run. This is bcos too much humidity in the air, if on for 24/7.
Calcium build up(whitish powder) and crusted, that kills the ultrasonic unit.
This is my experiences. I do know the importance of air cleaning. Just got into the hype of getting these products over these years. Everytime did not look at those products that costs over 3k or more.
And now, I have just got myself a venta airwasher lw45.
Its German tech using fan n water only.

I have seen reviews on this same model up to abt 10yrs back.... Still the same tech n design n long lasting.
Pro:
Save on buying filters.
Quiet with only 3fan speeds. At top speed at 8watt of power only. On 24/7.
Humidfy the air proper way, not using ultrasonic mists.
Cons : need to top up depending on the water level.
Clear the water every 2weeks or as needed.(dirty).
Thorough cleaning in 6mths.
Price oso almost the same as other electrical purifiers like sharp at tis promo price. Original 3999
Gonna get the bigger version soon, the lw60 model for my living room.
Another thing I have learned. Clean ur aircon at every 9-12months to remove molds. It will help the air quality, and prevent allergy alot. Never forget. Even getting all these stuffs, if the main culprit still spewing bad air. Never use old aircons, as its filtration can be bad, moldy n high electricity bill. Changing aircon every 5-7 years is a good guide.
Just to share my experiences.
