Purifier versus Humidifier
The humidifier also purifies air but at the same time, it also adds much-needed moisture to the air present inside which is lacking as the toxins stick to the air droplets and repel the moisture. This comes in extremely handy for people who suffer from nasal and chest infections, sinusitis, and other issues which are caused by dry air.
While it does remove allergens from the air, the basic aim of a humidifier is to remove dry air and relieve irritation. For it to function properly, one needs to add water to the machine on a regular basis. It is best suited for dry areas.
It’s possible to use both an air humidifier as well as purifier at the same time for added protection. Although, given the pollution levels breaching the dangerous mark, installing an air purifier should be a priority. A humidifier can remove certain irritants and make the air more pleasant to breathe, while a purifier would filter all types of toxins from the air.
If you are experiencing symptoms of sneezing, coughing, runny or scratchy nose alongside a nagging headache, going for a purifier would be the safest bet. But, if you suffer from sinusitis, getting a humidifier could solve problems greatly. more
