On a light blue background is the text “Example. ASHRAE: Residential common space, 25 L/p/s The Lancet: 6 Air Changes per Hour. By Air Changes Per Hour: 8 ft x 10 ft x 20 ft = 1600 cubic feet 6 air changes per hour x 1600 cubic feet = 9600 cubic feet per hour 9600 cubic feet per hour / 60 min per hr = 160 cubic feet per minute By occupancy: 3 people x 25 Liters per sec per person = 75 Liters per sec 75 L/s x (0.035 cu ft per L) x (60 sec per minute) = 157.5 cu ft per min In this example you would need a HEPA filters that is delivering at least 157.5 cubic feet of clean air per min. In the top right of the slide is a black graphic of a room with 3 people in it and dimensions labeled as 8 ft high, 10 feet long, and 20 feet wide.
On a light blue background is the text “If you want to see the math…” There are stylized graphics of lungs with flowers in them above and below this text.
On a light blue background is the text “How do I use this to choose an air purifier? filters.cleanairstars.com is an easy to use tool to help you search by what standard and noise level!” Below this is a screen capture of the 4 inputs filters.cleanairstars.com needs to make a list of air purifiers.
On a light blue background is the text “2) How quiet do I need it? Noise is the MOST OVERLOOKED part of using an air purifier. Noise is measured in decibels, dBA. 30 dBA - sensitive sleeper 35 dBA - sleep, quiet classroom, livingroom 40 dBA - average classroom, quiet office 45 dBA - noisy office, childacre, or classroom 50 dBA - loud childcare, gym, or restaurant 60 dBA - very loud bar or pub
On a light blue background is the text “Liters per person per second. Different organizations have put out different people-based standards. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) published a standard for control of infectious aerosols in 2023. This standard incorporates what activity people are doing, recognizing that more aerosols are released when people are sick, speaking loudly or breathing heavily. World Health Organization (WHO): 10 L/p/s The Lancet (a top medical journal): 14 L/p/s ASHRAE 241: Office, Residential home: 15 L/p/s Retail, Daycare, School, Medical Exam Room: 20 L/p/s Residential common area, Lecture Hall, Lobbies: 25 L/p/s Restaurant, Convention: 30 L/p/s Gym: 40 L/p/s Health care waiting room: 45 L/p/s.”
On a light blue background is the text “Liters per person per second. A liters per person per second standard is based on the number of people in a room, not the size of the room. Liters per person per second can be abbreviated both as L/p/s or Lps/person. A L/p/s standard is preferred by Share Clean Air MSP because it is based on how many sources of aerosols there are.” Below this text is a cute drawing of lungs in pink with happy faces on them, and to the right of the lungs is a graphic of 3 green 2 Liter soda bottles. Below the lungs and bottle graphics is the text “Average adult lung capacity is 6 L. That is 3 big soda bottles”
On a light blue background there is the text “Air changes per hour (ACH), ACH standards are about how many times per hour a purifier outputs a volume of clean air equal to the volume of the room. Different authorities have put out different standards. CDC: 5 ACH, Ontario Society of Professional Engineers: 6 ACH, The Lancet (a top medical journal): 6 ACH.” On the left side there is a graphic of 6 cubes in different pastel colors arranged in a circle with arrows pointing from one box to the next box in the circle.
On a light blue background is the top text “1) How much air filtration do I need? There are two types of standards:” On the left side there is the text “air changes per hour,” with a graphic of a room below it and then the text “Based on the amount of space” below the room graphic. On the right side there is the text “Liters per person per second,” with a graphic of two people with their arms up and then the text “based on number of people” below the graphic.
On a light blue background, there is a half circle gauge graphic pointing at 75%. Below that is the text: There are 2 questions to answer: 1) How much Air Filtration do I need? 2) How quiet do I need it?
On a light blue background, there is the text: A Guide To: Choosing an Air Purifier. Below that title is the Share Clean Air MSP logo.
Light blue background. Title reads "Important Notes!" Below the title is a large text box that reads "“Clean Air Stars is maintained by Dr Pieter Peach, an anaesthesiologist who sees cleaner indoor air as one of the sustainable, minimally disruptive interventions that can be cost-effectively implemented to reduce the impact of future waves of SARS-CoV-2 to help reduce the need for future restrictions. He started out his career as a microbiologist/virologist, and after medical school undertook postgraduate training in public health and epidemiology before training in anaesthesiology. This project receives no benefits from any of the businesses, services providers, or goods manufacturers mentioned.” https://cleanairstars.com/about/" Below the text box is a screenshot from cleanairstars.com/about that reads "Outdoor interactions are the safest. Interacting with people outside reduces the risk of transmission by up to 20x. / Improve mechanical ventilation...install HEPA filters"
Light blue background. Title: "The best part of this tool is that it tells you how many filters you would need and at what fan speed! And the cost of replacement filters!" On the left side of the slide below this is a text box that reads "based on size: 1800 cubic feet, 6 ACH." Below text box is a screenshot from filters.CleanAirStars.com that shows a small white air purifier. Below purifier, text reads "Levoit Core 300 - Speed 2. 3 units at above fan setting required for approximately 6 air changes per hr. 7.1 ACH (364m3/hr total) for 3 devices. Total Upfront Cost $300.

On a light blue background, the title reads "Filters.Clean.Air.Stars.com is a great tool to help find air purifiers!" On the left half of the slide, a text box reads "By room size." Below that text box is a screen capture from filters.CleanAirStars.com that reads "Acceptable noise level: 40 dBA. Litres/person/second or Air Changes per Hour (ACH) target. What are L/p/s and ACH? (link to more info): 6 Air Changes per Hour (ACH). Room volume (Width x Length x Height) in m or feet: 300. m3 or cubic feet: cubic feet." On the right half of the slide, a text box reads "by number of people." Below that text box is a screen capture from filters.Clean.Air.Stars.com that reads "Acceptable noise level: 40 dBA.

On a light blue background, the title reads "The noise volume of a purifier is measured in decibels (dBA)." On the left side of the slide is a screen shot from cleanairstars.com that reads " Decibel (dBA) limit guide / Mighty Bullfrog 12:38 PM (0 minutes ago) to Meridith Tolerability of noise from air filters depends greatly on existing ambient noise levels. The below recommendations are a guide only. Some devices may have less tolerable noise characteristics even at low dBA. 30-40dBA Sleep / 40-45dBA Classroom, Quiet Restaurant & Office / 40-50dBA Loud Office & Childcare / <60dBA Loud Restaurant, Gym / >60dBA - Acceptable for loud environments." The right side of the slide reads "Let's use 40 dBA, equal to a quiet office."
On a light blue background, the title of the slide reads "There are good standards based on the size of the room or the number of people". The right side of the slide reads "Let's use an average US living room: 300 square feet 4 people". To the left is a screen capture from itsairborne.com that reads "WHO recommends 10 liters/second/person Lancet COVID-19 Commission recommends 6 air changes per hour or 14 lps/person. 6 ACH is used here for comparison, but places with high density could have far greater values. Ontario Society of Professional Engineers recommends 6 air changes per hour (ACH). There is also a recommendation to use upper room UV in high density spaces which can lead to more than 20 air changes per hour. CDC recommends 5 air changes per hour"
On a light blue background, the top text reads "There are two key things you need to know." The middle text reads "1. Room size or occupancy 2. Acceptable noise levels" In the lower third of the slide there is an icon of three people in a room to the left and an icon of sound waves and a ear to the right.
