Is this air purifier good?

Suppaduppa · Apr 27, 2014

Im looking for a air purifier to keep my room reasonably clean. No way im spending a ridiculous amount for it like these IqAir ones, so this one seems decent and affordable:

Im not sure about the whole negative ions thing so im going to buy it without that feature. Or Should I get the model that also delivers negative ions?

what do you think?

Hi
Air purifiers are essentially just a fan and a filter and so should not be very expensive,the one you are looking at should do a good job.
I have yet to see any scientific evidence for the health benefits of negative ions, most of the benefits that are claimed are just marketing fluff.However there is some evidence to suggest that negative ions can reduce static electricity but this would only occur near the exhaust of the fan.

Well here is a legit study on negative ions:

Controlled trial of bright light and negative air ions for chronic depression. BACKGROUND: This randomized controlled trial investigates the efficacy of two non-pharmacologic treatments, bright light and high-density negative air ions for non-seasonal chronic depression. Both methods have shown clinical success for seasonal affective disorder (SAD). METHOD: Patients were 24 (75%) women and 8 (25%) men, ages 22-65 years (mean age +/- S.D., 43.7 +/- 12.4 years), with Major Depressive Disorder, Single Episode (DSM-IV code, 296.2), Chronic (episode duration > or = 2 years). Patients were entered throughout the year and randomly assigned to exposure to bright light (10 000 lux, n = 10), or high-density (4.5 x 10(14) ions/s flow rate, n = 12) or low-density (1.7 x 10(11) ions/s, n = 10, placebo control) negative air ions. Home treatment sessions occurred for 1 h upon awakening for 5 weeks. Blinded raters assessed symptom severity weekly with the Structured Interview Guide for the Hamilton Depression Rating Scale--Seasonal Affective Disorder (SIGH-SAD) version. Evening saliva samples were obtained before and after treatment for ascertainment of circadian melatonin rhythm phase. RESULTS: SIGH-SAD score improvement was 53.7% for bright light and 51.1% for high-density ions v. 17.0% for low-density ions. Remission rates were 50%, 50% and 0% respectively. The presence or severity of atypical symptoms did not predict response to either treatment modality, nor were phase advances to light associated with positive response. CONCLUSIONS: Both bright light and negative air ions are effective for treatment of chronic depression. Remission rates are similar to those for SAD, but without a seasonal dependency or apparent mediation by circadian rhythm phase shifts. Combination treatment with antidepressant drugs may further enhance clinical response.

Why what I Found is a Korean Page? You mean that small air purifier?

Well, whatever, here are what I want to say:

There are generally two kinds of air purifiers: one is filter kinds, I mean with a(or more) filter to remove dust, smoke, odors from the air when the air flow pass through it. The most effective filter is HEPA filter and the air purifier with a HEPA filter inside is also called as HEPA air purifier with a price of around >$150.The other kind is using negative ions to charge the air particles and get them stuck together in which way purifying the air. General speaking, the HEPA one is much more effective in most kinds of air pollutants. While the ion type is good at absorbing fine particles. The more comparison between air purifying technology: http://...main-types-air-purifiying-technology/

And yes, there are some air purifiers combined the filter way and the negative ions way. Compared with the two types mentioned above, they should have better effect in air purifying. But please attention that the prices and parameters of air cleaners always have big differences between different brands. So, I advise you only choose the big brands, like honeywell, whirlpool , etc..
