Documented Research

Our air purifiers are based purely on documented studies and research with sustainability and your wellbeing in mind. While many of our competitors make claims without proof, we only provide benefits that are based on documented studies, so you can really see how big of an impact our Pulmonologist Air Purifiers can have on your life.

Citations and links to the research are available below, so you can freely verify the information.

We are extremely careful with the products we put our name on. Because we want to make sure every product we put our name on works for you, we only select the best. Our philosophy is important to the success of our company.

Air Purifiers and children with Asthma
Clinical study:

To evaluate the effects of air purifiers on the concentrations of indoor air pollutants and on asthma control in children.


Asthma severity was assessed in terms of both symptom and medication scores acquired using a daily questionnaire. The higher the score, the better the symptom or the less frequent the use of medication. Peak expiratory flow rate and fractional exhaled nitric oxide were also measured.

The primary endpoints were changes in indoor air quality, asthma severity, lung function, airway inflammatory, urine microbiome, and phthalate after the installation of air purifiers. PM2.5 and CO₂ were measured as indoor air pollutants.


The study suggests that air purifiers benefit medication burden in children with asthma by reducing PM2.5 levels.


Air Purifier therapy in allergic rhinitis
Clinical study:

Efficacy of air purifier therapy in allergic rhinitis. With the rising prevalence of allergic rhinitis, the utility of indoor environmental management deserves increasing scrutiny. This research aims at evaluating the ability of air purifiers to be a therapy of allergic rhinitis.


Aiming at evaluating the ability of air purifiers to be a therapy of allergic rhinitis. Dust samples were collected with a vacuum cleaner and the dust collector assessed for allergen content. Additionally, static dust collectors were left in place all month to collect dust by sedimentation. Particulate matter (PM) was assessed in terms of PMindoor/outdoor ratios.


HEPA air purifiers can effectively reduce PM and HDM allergen concentration in the indoor air, and thereby improve clinical manifestations of patients with AR.

Single-Chamber method assessment of air purifiers
Clinic study:

Assessment of air purifier on the efficient removal of airborne bacteria, staphylococcus epidermidis, using single-chamber method.


We evaluated the efficiency of an air purifier using the single-chamber method for the effective removal of airborne Staphylococcus epidermidis, a nosocomial infection-causing bacterium. The microbial sampling was conducted via the air sampler method, and the reduction in S. epidermidis growth was monitored by performing three consecutive tests. In addition, the particle size distribution in the test chamber was found to range from 0.3 to 5.0 μm, and a subsequent decrease in large-sized particles was observed with the operation of the air purifier, which is the size similar to that of suspended airborne bacteria. This can be used to assess the performance of the air purifier by calibrating the natural reduction value to the reduced operation value.


The single-chamber technique is a promising approach for analyzing the removal efficacy of airborne bacteria from indoor air.

Air Pollution and Mortality in the Medicare Population
Clinical study:

Analysis and assessment on Air Pollution and Mortality.


Studies have shown that long-term exposure to air pollution increases mortality. However, evidence is limited for air-pollution levels below the most recent National Ambient Air Quality Standards. Previous studies involved predominantly urban populations and did not have the statistical power to estimate the health effects in underrepresented groups.


In the entire Medicare population, there was significant evidence of adverse effects related to exposure to PM2.5 and ozone at concentrations below current national standards.
