How do you change the filter? My in-laws have lost the instructions for their purifier.

Lancaster air purifiers can have different models and designs, so the exact location and method for removing the filter may vary. However, I can provide you with some general guidance that should help you locate and remove the filter in most air purifiers.
1. Check the user manual: The first step is to consult the user manual that came with the air purifier. It typically contains specific instructions on how to access and replace the filter. If you don't have the manual, you can often find it online on the manufacturer's website.
2. Look for a filter compartment: Most air purifiers have a designated compartment or access panel where the filter is located. It may be on the back, side, or front of the unit. Examine the air purifier and look for any labeled panels or compartments that indicate the filter's location.
3. Remove the filter cover: Once you've located the filter compartment, you'll need to remove the cover or panel to access the filter. The cover may be secured with screws, clips, or latches. Use a screwdriver or your hands to undo the fasteners and carefully remove the cover.
4. Take out the filter: After removing the cover, you should see the filter inside. Depending on the model, the filter may be a single unit or consist of multiple layers. Take note of how the filter is positioned before removing it to ensure you can correctly replace it later.
5. Follow any additional instructions: Some air purifiers have specific instructions for removing the filter, such as pressing a release button or sliding it out from a designated slot. Refer to the user manual or any labels on the unit for any additional guidance.
6. Clean or replace the filter: Once the filter is removed, you can determine whether it needs cleaning or replacement. If it's a reusable filter, check the manufacturer's instructions on how to clean it properly. For disposable filters, it's generally recommended to replace them according to the manufacturer's guidelines.
Remember to consult the specific user manual for your Lancaster air purifier model to get accurate instructions tailored to your device.

Hi josephjohn,Here are instructions on How to Change Cabin Air Filter in a Toyota. It is recommended to replace this filter at every oil change.

Why don't you check it every week or two

You can by the filters at target and the replacement filter should come with instructions on how to change it

Manual can be found here: http://www.kaz.com/kaz/support/manual/?ProductManualAction=renderProductManualById&ProductManualId=47a366c04a65e77c69850893b979e142

the lights are the ionizer light, the filter indicator light which is the light that will come on when the filters need to be changed, ionizer control button, the speed control and the power light.

Filter lights on your Air Purifier http://www.fastbrowser.net/netpicker/Filter-lights-on-your-Airifie.htm One of the best things about your IQAir Air Purifier is that it has warning lights to tell you when to change the prefilter, gas or hepa filters. Of course how long they last depends on your pattern of usage. For the initial 80% of the filter life the control panel will display a green light next to the corresponding filter on the outline of the unit. When the orange light goes on it does not mean that the filter needs to be replaced immediately but that there is 20% of useful life left. IQAir gives you plenty of time and the machine will tell you how many hours you have left. Once the number of hours gets to within a few hours remaining the orange light will then change to red. It is at this time you should change the filter. If you forget to change it and there are no hours left the hours will go into the negative displaying how many hours you have gone over and the red light will change to a flashing red light.

Just in case you have lost the manual like one of our customers, this is how you reset the filter lights:
1. Press the menu button ( 7 times) until you get to where the display says new filter.
2. Press the enter button and hold it down for 3 seconds and a number 1 will be flashing after the words new filter on the display. This flashing number is so you can enter which filter you have changed. Filter number 1 is the pre-filter, filter number 2 is the V-5 gas filter, and filter number 3 is the Hepa filter.
3. You change the number for the filter by pressing the up arrow button.
4. Once you reach the correct filter number you press the enter button and the control panel will display a question mark after the words new filter on the display. Below this it will say, E = Yes M = Cancel. If you wish to cancel the entry so it does not reset a new filter life, simply press the Menu button.
5. If you want it to reset the filter life for the changed filter, simply press the Enter button. Once this is done, the filter light will change back to the green light, which will show the filter has been changed. If you go to the remaining filter life on the control panel for the filter number you just changed, you will now see the remaining life of the filter in hours has been reset.

Noggin's solution is correct.  My copy of the BAP825 manual says to poke a paper clip into "the hole marked RESET."  There is no hole marked 'reset' on the air cleaner.  Thanks, Noggin!
