You can purchase from either of these, xiaomistore.pk or mistore.pk
(Not daraz)
I purchased from xiaomistore.pk
I waited for more than month last year to get it (it was out of stock)
Click on notify, purchase it when it arrives
Yes a lot, I've tried triamcinolone acetonide nasal spray and Fexofenadine and cetirizine dihydrochloride, but all of these didn't help much, every second day sneezing, post nasal dripping, watery eyes and itchy nose,, but after purifier, no. of episodes are much lower, to me it's 100% value for money
(Btw still using nasal spray and cetirizine)
A normal person may not feel such difference but it's a blessing for allergic patients
