I had spent quite sometime looking for a suitable air purifier for my mom and the kitties. After visiting electronic shops and checking out online and also sending an endless list of queries to Jeriel ( from Trident Air ), I decided on Trident Air - Bliss & Mini after confirming the functionality and coverage area : Mini for the living room and Bliss for the bedroom. After using Bliss, we find that the air is much fresher, the room much cooler and the smell from the litter box under control. The senior kitty in the room used to have teary eyes but after using Trident for a while, she does not have teary eyes anymore and rarely get to hear any sneezing from her. It is important to get the right product to keep the environment clean for her. Bliss is also small, compact and powerful and its sleek size makes it fitting for most HDB bedrooms. The same applies for Mini and the living room is an important area as it is a gathering place for the family. For maintenance, I find it easy to wash, clean and dry the Air Purifier. It does not take up much time but I do cater for longer drying time to ensure that it is dried properly before powering up. After using 2 APs from a well-known brand and cannot find its filter, it is a blessing that I can now wash the filter without worry if the filters will still be available in the next 3 - 5 years. For Support, Jeriel is doing a great job - answering to queries early in the morning to supporting clients over the weekends with helpful information.
