My humidifier HMW-450 does not work properly. I've cleaned it and replaced the filter but does not automatically work and when it does it's for short durations of 1/2 hour. Should I replace my humidifier?

PowerPure 3000 Ultrasonic Humidifier


This review says it has a permanent ceramic filter that cleans the water in your tank. Another review said the ceramic filter softens and cleans the water.

That model appears to not require replacing the permanent ceramic filter. Other models have filters that need to be replaced.

Hello.

The GE humidifier adds a continuous stream of cool mist intothe air, giving moisture to dry air due to cold weather or dry climate or tohelp those who desire additional moisture because of respiratory problems orallergies. Sold online and in many department or home retail stores, thehumidifier requires regular cleaning and maintenance for proper functioning andto help keep mineral scale or bacteria from growing in the humidifier. ·1 Connect the power cord on the GE humidifier firmly to a power outlet if thehumidifier is not working. Replace or reset the circuit breaker as necessary.Turn the power switch to "On" if there is power but the unit is notoperating. · 2 Fill thewater tank to the "Fill" mark if the mist output is low or notpresent. Wait 15 minutes after filling the tank and before starting thehumidifier to allow the wick filter to absorb the water for proper function.Turn the humidistat knob to a higher setting for higher output. · 3 Check the capon the water tank and close the cap firmly. Check the rubber tank cap ring onthe cap and reseat firmly to help provide a better seal. · 4 Replace thewick filter with a new wick filter, available through General Electric, if thewick filter inside the base turns brown. Replacement parts may be ordered bycalling 877-207-0923. · 5 Clean thewater tank with vinegar and a soft brush if the water begins to get cloudy.Rinse well before refilling with water. Use cold water in the tank, as warm orhot water may make the water appear cloudy. · 6 Loosen thetank cap slightly if the humidifier cycles on and off unexpectedly. Turn theknob to a higher or lower setting. Thanks.

Hope this helps, check and see if humidistat is set to 35% humidity and that bypass damper on humidifier is in the open position or winter position.(humidistat is usually located on cold air return duct near furnace). Next, replace humidifier media pad, remember to replace media pad (filter) annually, you also may want to clean any lime deposit out of humidifier housing with a solution of warm water and white vinegar before installing your new media filter.Remember to turn power off at side of furnace when cleaning humidifier and replacing media. Before installing new media turn power back on to furnace, set humidistat to the on position, turn furnace thermostat above room temp., and inspect humidifier to see if water is running from top,(you may want to have a bucket under humidifier when checking for water), if you see water running, turn power back off to furnace, properly install new media filter, reconnect humidifier cover & set humidistat to 35%. If you do not see water present, check water supply valve to humidifier and make sure its turned on. If water supply valve is open, then check water supply tubing for blockage.And the last things to check is to make sure all registers through out your home are open and not blocked by any objects, also make sure furnace filter is cleaned, if none of this works refer to installation manual to see if humidifier was sized and installed properly, Good luck.

Replace humidifier media pad (filter) with a new one, and clean interior of humidifier housing with a solution of warm water and vinegar, also replace or clean furnace filter, Good luck.

REPLACING THE FILTERS
Through normal use, waterborne minerals and sediment
become trapped in the wick filters. The harder your
water, the greater the amount of minerals in the water,
and the more often you will be able to monitor the life of
your filters in your humidifier.
You will be able to monitor the life of the filters in your
humidifier by checking the FilterCheck® Indicator. After
60 minutes of use, FilterCheck® Indicator will move and
indicate your filters condition. New filters will register in
the section reading Good filter. After frequent use of your
humidifier, the FilterCheck® Indicator will let you know
when the filters need to be changed, see Figure 2.
When the needle is in the CHANGE section, this means the
proper amount of moisture is not getting into your air due
to the excessive minerals and sediment that have become
trapped on your filters. At this point, you should replace your
filters. It is important to change your filters as
indicated to obtain stated performance level.
To replace the filter, follow the steps below:
1. Turn the unit off and disconnect from the electrical
outlet.
2. Remove the tank and main housing to access the base.
3. Remove the wick holder from the base of the humidifier.
4. Remove each individual wick and discard. Do not
remove rivet, replacement wicks come equipped with
rivets for easy replacement.
5. Follow the weekly cleaning instructions.
6. Insert new filters into each section of the wick holder
making sure the rivet attaches to the wick holder
securely.
7. Do not use wicks without rivets as this will not
produce the units intended output.
8. Replace the wick holder into the base and replace
main housing and then tank.
9. Repeat Operating Instructions.
It will take about 30 minutes for the humidifier to reach
maximum output.
Cheers!

need it it will be ready, flush water system with clean water with a dash of bleach mixed in. The bleach will inhibit any mildew or moldClean fan of collected dirt, remove and replace filters so when you needed again it will be ready..make sure all water is drained and let unit thoroughly dry outdoors. Good luck

A leaking humidifier is a sign that the unit's filter needs to be cleaned/changed. I had the exact same problem on this model.

Most water panels are generally replaced once a year on flow through humidifiers.

I usually just balance the tray upside down on top of the base and fill the edges with vinegar. You could also put the the tray in a bowl filled with vinegar and submerge the whole thing.

nvm :)

Features: Low Maintenance:
* Regulated Release ™ System - eliminates stagnant water while preventing mineral build-up on the wick or filter, which can impede performance in ordinary evaporative humidifiers.
* Dishwasher-Safe, Easy-Clean Base and Tank - with antimicrobial agents molded into plastic parts to inhibit the growth of microorganisms.
* PermaWick ™ - permanent wick never needs to be replaced, saving up to $45 per year in replacement filter costs.
* Top Down Water Dispersion - evenly disperses water from the top over the entire wick to prevent mineral build up that can impede performance.
