How we Test Air Purifiers
Here at Air and Purifier First, we strive to provide you with honest reviews and thorough testing processes. Each review aims to provide utmost clarity on the air purifier’s capabilities, helping readers understand its worth. In the following sections of this article, we outline the step-by-step process and systematic reasoning behind our selection of methods for each air purifier, as well as how our review can help you make an informed decision.Air Purifier Testing Methodology OverviewTo best understand the worth of an air purifier, we use and abuse them for reviews at residential structures. Rather than testing the devices in a lab, wherein they can be controlled for a set of criteria, we assess how they will work in the user’s environment. We believe that this will provide the clearest picture for our users, helping them understand the value of the air purifier in their daily lives.Every air purifier that we review goes through a set of predetermined protocols meant to assess their: 1. Effectiveness2. Sound Output3. Running Charges4. Price Point5. Effectiveness of InstructionsEach of these will be scored on a scale of 1 to 10, and the average of the scores will form the final score of the air purifier. Performance TestsTests to evaluate the air purifier’s efficacy involve removing particles, cleaning a smoke box, and neutralizing certain odors. Following is a detailed description of each of these tests and their associated procedures:Particle Removal TestsPreliminary tests were conducted using the Temtop LKC-1000S air quality monitor to determine the impact of PM (Particulate Matter) 2.5 and PM 10 particles and other volatile organic compounds. The tests were conducted in controlled environments. The air purifiers were set to their recommended coverage area (CADR) and allowed to operate at full blast for 60 minutes. Following that, the air purifiers were evaluated for their ability to improve air quality, ensuring the efficiency of the air purifiers in removing dust, pollen, and other allergens.Testing Locations:Small Air Purifiers: 120 sq. ft. (11 m²)Rooms with Regular Use:194 sq. ft. (18 m²)Standard Testing Room: 320 sq. ft. (30 m²)Air Purifiers for Larger Rooms:560 sq. ft. (52 m²)Air Purifiers with Exceptional Power:** 730 sq. ft. (68 m²)Smoke Box TestsWe place each air purifier inside a glass enclosure, generate smoke, and record the time needed for smoke removal at maximum setting. This test reveals effectiveness during heavy pollution.Operating CostsWe record power consumption at every fan speed to gauge each unit’s electricity cost.We measure power consumption with a power meter and record usage in kilowatt-hours (kWh). We use an energy cost of $0.12 per kWh for calculations. You can also use our power consumption calculator to estimate costs based on your rates.Cost of Replacing FiltersIn addition to power costs, there are recurring expenses associated with replacing filters, a common cost with air purifiers. With replacement filters, we also seek third-party options to keep replacement costs low over the product’s lifespan. Measuring Noise Levels For many users, the amount of noise a machine generates is important. For noise measurement, we use a dedicated sound level meter, which measures sound in decibels (dB). Each purifier is tested at multiple speeds to determine the noise produced at both the lowest and highest purifier speeds. Noise Levels Breakdown:Whisper-quiet room (20 dBA) Soft music (30 dBA) Home computer fan (40 dBA) Light a/c with some outside traffic (50 dBA) Typical conversation (60 dBA) Noisy room with flushing toilet (70 dBA) Alarm clock, rushing water, or inside airplane (80 dBA) We assess if air purifiers are suitable for bedrooms and quiet spaces.Features EvaluationTo determine the overall rating for each air purifier, we examine the design, effectiveness, and ease of use. Here are the points we consider:1. Smart Features: Does the purifier come equipped with a smart application that allows remote access or voice controls through Alexa or Google Assistant.2. Design: Is the purifier aesthetic, functional, and easy to transport, while also complementing the furnishing of the interior?3. Ease of Use: Are the controls simplified? Does the purifier come equipped with useful features, such as auto mode, filter replacement reminders, and sleep mode?4. Warranty and Customer Support: Comprehensive customer support and a lengthy warranty period are positive indicators of reliability and confidence in the brand. We examine the warranty period and also assess the customer service offered by the brand. Final RatingsAfter we complete the air purifier tests, we compile all the results and calculate an average score. Then, we assign the score according to the rating system blood scores. 9.5 and more: Outstanding Score 9.0 – 9.4: Excellent Score 8.0 – 8.9: Good Score 7.0 – 7.9: Fair Score 6.0 – 6.9: Mediocre Score 5.0 – 5.9: Poor Score 4.9 and less: Terrible Score Why Trust Our Reviews?The methods we used for testing have both technical and hands-on experience. This means we use objective data and physical testing feedback, ensuring that the reviews we create have as few mistakes as possible. Our tests regarding allergies, pet dander, and mold provide you with the most precise and reliable results possible for the air purifier. We hope this overview shows how we test and why you can trust our reviews to help you choose the best air purifier for your home.
