<div class="bvseo-answer" data-answerid="7990380">
Hi Msrogersjas! Thank you for choosing Holmes&reg;️. The months and years on the air purifier is called the Filter Reminder Dial, this would help you keep track of when to change the filter. Turn the Filter Reminder Dial to select the current month you are replacing the new filter(s). This will serve as reference for when filter replacement is needed. For example, filters with a 12-month filter life: set the filter reminder dial to 12 months and keep track on how long a filter has been in use. We hope this information helps. Thank you and have a good one!

Hi there, wolly! Thank you for choosing Holmes&reg;️. We hope you are doing well and safe. We are more than happy to assist you with your inquiry today. Every few weeks, check the condition of filter(s). The VisipureTM Filter Viewing Window is a lens which allows you to get a clear view of the dirt being collected in the filter. The Filter Reminder Dial also helps you keep track of when to change the filters. To properly place your filter, align the clips on the side of Aer1&reg; filters with rails on the inside of the purifier unit. Gently slide the filters onto the rail. We hope this information helps. Have a wonderful day!

How much energy does this unit use? I bought one a couple of months ago and my electric bill shot up. What is the breakdown of energy usage (speeds 1, 2, and 3) and how much energy does the ionizer use on top of that?

<div class="bvseo-answer" data-answerid="7542903">
Hi ES23! Thank you for choosing Holmes&reg;, we hope you are healthy and staying safe. We are more than happy to assist you. Power of an air purifier is about 50 watts, you could run it restlessly for 20 hours to increase one unit. Compare to the general power of a light bulb of 60 watts and a computer of 365 watts. Your air purifiers are much more energy efficient than most of your popular electric devices. The rated power of a modern air purifier is 50 watts on average. That means it consumes 18 kWh of electrical energy in a month based on daily 12 hours of usage, which will cost $2.2 at 12 cents/kWh energy rate. We hope this information helps. Have a good one!

<div class="bvseo-answer" data-answerid="7542723">
Hi Mirek! Thank you for choosing Holmes&reg;, we hope you are healthy and staying safe. Allow us to assist you with your concern. We advise that the best placement of the air purifier would be close to a window or doorway. Through windows and doorways, the airflow moves freely and is able to lift dust, molds, and any other particles and quickly spreads it in your room. You may need to front face the air purifier to the opposite way of your room, and should at least be 2-5 feet away from the wall. We hope this information helps. Have a wonderful day!
