Question about Hunter HEPAtech 715 (2 Pack) Air Purifier

1 Answer

Model 717 no longer working...can this be b/c i never changed filter?

I believe I've changed the pre-filter once since I've been using this Air Purifier (probably a year old). Recently, the Air Purifier stopped working (i.e., when I plug in AC power, no response in the LCD display - I remember that i should at least see something when it boots up).

Question: Is my problem because I've never changed my filter??? Are there any additional troubleshooting steps that i should take??

Pleeeeaase help...thanks in advance!

Re: Model 717 no longer working...can this be b/c i never...

Honestly, whether there's a filter problem or not, the screen should boot up period. If you still have your manual that came with your machine, look up troubleshooting steps provided by the company. (might want to take a look at the warranty for a possible repair under manufacturers warranty). A very familiar hard reset is to unplug the machine, and hold down the power button for a minute (yes, unplugged) then release, plug it in, and try to turn it on. if that doesnt work, I'd attempt to unplug, press all the buttons on the machine once individually, then try again plugging it in, and turning it on. Try all this in a seperate outlet... If it fails, definately call their customer support, cus it may be a defect in the chipset.

I want to change filters. please help

Hi and welcome to DixYa, I am Kelly

The only two parts requiring any service are the activated carbon pre-filter and the HEPA filter. No tools are needed. To change either filter, disassemble the unit as shown.
1. Loosen the carrying handle by turning it counterclockwise and lift filter cage cover from unit.
2. Lift HEPA filter and activated carbon pre-filter from the base.
3. Remove the fasteners from the activated carbon pre-filter and remove it from the HEPA filter cartridge.
4. Replace filter(s) as needed, and discard used filters.
5. Wrap the activated carbon pre-filter around the HEPA filter cartridge and secure it with the fasteners provided

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

You have a Honeywell air filter. Turn it over and there is a big handle which is a screw in the middle. Unscrew it and then lift the entire unit up without the outside screen protection. The filter will have a black pre-filter attached by velcro. Remove it, take outside put on the grass and hose out against the flow of air. (squirt from the inside out to remove stuff). Then use vacuum to blow the filter from inside to the out. Then vacuum the filter from outside in. Let the pre-filter dry. re-install in reverse. If there is a warning light, run on full, then push the warning reset for 10 seconds or more to turn it off.

Can I just change the pre-filter because it is full of dust and not replace the main hepa filter

Yes, but keep in mind the warranty requirements:
To receive the full benefit from your Defender ®, replace your filters regularly. • Every 6 months, replace your Enviropure® Charcoal Filter. • Once a year (for Perpetual Warranty*)/up to every 3 years (depending on usage), replace your Medi-Filter® Cartridge.
*Refer to the warranty for information on warranty extension(Perpetual Warranty)

How to change the flter

Turn off the unit and unplug it. Turn the air purifier on it's side and unscrew the locking mechanism (turn counter-clockwise) on the base of the unit. Remove the base assembly from the unit. Remove the filter assembly and find the seam of the pre-filter. Carefully separate the fastener and then remove the pre-filter from the HEPA filter.

Discard the filter(s) being replaced. Then remove the new filter from the packaging and discard the packaging and plastic. Carefully wrap the pre-filter around the HEPA filter so that the ends meet. Fasten the ends together with the fastener.

Place the filter assembly in the air purifier and reattach the base. Then tighten the locking mechanism. Turn the unit right side up, plug it in and turn it on.

I hope this helps.

Hunter 730 carbon pre-filter replacement orange light

Filter lights on your Air Purifier 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.
