Protect Extended Life Replacement Humidifier Filter 6 Model WF620

A previous reviewer was pretty crabby saying that this filter is sold for much less elsewhere. Actually, s/he specifies a different model # and that model can be found much less expensively on Amazon, too. I just didn't want this error to drive people away.

The price for this product on this site is 3X the price for the same product on other sites. Simply enter "Model WF620" in any search engine and you will be directed to a number of reputable sites selling this product for one-third the price. DON'T MAKE THE MISTAKE OF BUYING THIS PRODUCT FROM THIS RIP OFF SHOP.

350 cc Bubble Humidifier - Dry

I have a nice quiet Everflo Oxygen Concentrator, but it was hard to tell since all I could hear was the water bubbling in the humidifier bottle. I got this bubble humidifier after my 3rd generic bubble humidifier replacement in a short time, they kept cracking; the water would drain all over the floor and I didn't know right away that I wasn't getting enough oxygen until I felt sick. I decided to investigate other products.

I have been using Salter tubing, swivel connectors & nasal canulas and saw their bubble humidifier. Right away some things made sense, for instance water kept going up the tubing and into my nose, very unpleasant; they call it rain out because of the dome lid design, rain out is minimized. The "connecting tower design" increases resistance to damage and seems much stronger than my no name bottle. Also, I had to constantly wipe my nose with my previous humidifier, but with the Salter Labs bubble humidifier hydrates my breathing passages but doesn't overdo it. It's almost like the water droplets are much smaller. The icing on the cake is that this bottle is so much quieter!

I plan to be using only these from now on!

Essick Air EP9 500 Whole House Evaporative Digital Pedestal Humidifier, Nutmeg

This is a very nice looking unit. It runs very quietly at it's lowest fan speed and can put out a lot of moisture at it's highest (10) speed. The only drawback we have had is that it is difficult to see the water level. At first we overfilled the unit and had about a quart of water overflow onto our carpeting. At that point we started taking the unit apart (it is 2 pieces) by lifting the outer shell off. We then learned to just use a flashlight to look into the tank with the front filler door open. It comes with an attachment that fits the filler door when open to extend the opening, but we do not use it. It is a lot more convenient to fill versus pulling the tanks out of our old unit. Would buy again.

My ex is a humidifier person, so I learned from the best. This is a sweet humidifier. Nice and seemingly accurate and well engineered controls, nice marble top and perfect for my purpose. Gets loud once you get into level 5-10. Level 1 is quiet and gets my 12 x 16 master bedroom about 55% (I'm in uber-dry Las Cruces, NM too...) Worth the $.

Extech PH110 Waterproof ExStik pH Meter

Good:

The PH110 is accurate and cheap. I am able to get repeatable flavor and texture when I make cheese, because I can hit all my markers.

Bad:

The PH110 requires fiddling every time I want to use it. It requires at least one calibration when I take it out of the cabinet. Then if I wait more than a couple of hours between uses, it requires another calibration. Calibration isn't difficult, but it can get pricy because you have to buy pouches of calibration solution. I put the solution in a tupperware bowl and reuse it for a day or two.

Ugly:

A couple of times, I had to remove the batteries to reset it because it locked up during a calibration.

I bought this to use for cheese making, and it has fulfilled all my expectations, including the ability to check the pH of the cheese itself, rather than just the whey as most other meters are limited to.

I can only hope that it will prove as reliable in the long run as it has in the short run, providing reliable information to 2 decimal points, which comes in very handy.

I love it and would recommend it to anyone needing such accuracy and reliability.

This meter did not calibrate, even after following the troubleshooting instructions directly from Extech's website. I turned the meter upside downand tapped on the tip with the pad of my finger and the glass on the tip broke. I didn't know glass could be this thin (it broke) not durable in any way shape or form. Not sure what environment this was designed for but certainly not mine. I shipped it back for a refund. If you ever dropped this it would surely break the glass.

Hamilton Beach True Air Allergen-Reducing Air Cleaner

A brief video of the sounds of this air purifier at different speeds.

Overall, works well as many have stated. Hope this helps. Peace.

I bought this product for my son. He's eight years old and suffers from allergies. He woke up every morning sneezing, and with a stuffy nose. I was looking for an alternative to giving him allergy medication every day. We keep it on the desk, right next to his bed. It's incredibly quiet and it has helped his allergies a lot. After about a month of constant use on the medium setting, I vacuumed the filter. It was filty. I was very impressed with how much dust it pulled from the air.

Our daughter has allergies and we've tried several different air purifiers. This is by far the best we've tried. It is much quieter than others, compact size, the filter is permanent, and it works great. We are getting another one for another room.

I received my item (though late, Thanks Amazon), and apparently all my research into an air cleaner has paid off. This little guy does exactly what it says and works like a charm.

Here's why I bought it. I wanted an air cleaner for a medium to small sized room where I keep my cat's litter box. Normally, it doesn't smell, but about the day it's time to change it, I can smell it. Now, I don't want to smell it ever, though I keep my kitty box schedule in tact. Anyway, this air cleaner is so quiet on Whisper Mode that I literally cannot hear it. I even put it in my roommate's bedroom, just to see if she realized it was in there, before moving it to its final destination. She had no clue.

The model has 3 speeds, but the Whisper Mode is fine for continuous daily use. Sure, you can turn it up, and you'll hear it's low whirrrrrr, but that's to be expected.

Another reason I bought it is that it IS a HEPA quality cleaner. But I don't have to buy replacement filters--ever. This one has a "permanent" filter, which I didn't even know existed. To clean it, it says about once every 6 months to just use your hose and brush attachment of your vacuum cleaner and suck it out. Really? That's awesome! Why don't ALL HEPA filters do this. That feels like such a waste. I'm not allergic to anything, but my purpose for this is to keep the area near my kitty box smelling like air, and not horrid ammonia. Cats are so gorgeous, but like newborn babies, they sure can produce some of the foulest smells!

So: I am in love with this baby. Thanks Hamilton Beach!

Wanted a small appliance like this air purifier to use in seperate bedrooms to stop dust/pollen/dander/dust mite poop or whatever debris lingers in the air from being inhaled during my loved ones sleep, this one works great and appears to really remove debris from the air. I am sure that higher priced air purifiers with expensive replacement filters work much better but we did not want to pay $$$ plus $$ for replacement filters three or four times a year.

On low the fan can barely be heard, medium is like a normal fan noise and is not bothersome at all (all of us stated we actually enjoy this white background noise), high would be too loud for most sleepers. Each of us that has one in their bedroom merely turns it on high an hour before bed, then turn it to medium for actual sleep time.

Can be layed on its side or stood straight up which is a nice choice to have based upon personal preference.

Filter is easy to remove and clean, just wish HB would have made the material surrounding the filter a bit more sturdy as it is just thin cardboard so you have to be careful not to damage it when cleaning. I use the brush attachment on my vacuum cleaner and it works great. I highly doubt this filter would be permanent like HB claims after many repeated cleanings so we expect to replace it every couple of years just for good measure!

Overall I gave it 5 stars but it surely would not compete with a much more expensive winix or austinaire, regardless, IMHO, it is an exceptional value for the price.

Edited to add: FYI, to dramatically enhance the effectiveness of this unit, go to a Lowe's or Home Depot type store and purchase a sheet (hammock filter) of the 3M filtrete filters (about $18 bucks, the good ones, the type used to put over window airconditioners to trap allergens/dust). Cut a square large enough to put above/over the permanent filter on this unit, the filtrete filter then takes most of the particles before it even hits this unit's permanent filter. I have done this for 4 months, it does not damage or negatively affect the unit's motor and you will be amazed how much stuff these little units take out of the air (with two filters, a filtrete one and the one that comes with the unit). Best part of all, after two months, merely discard the 3M homemade filter and replace it with a new cut-out. I also discovered that I can merely lightly tap the unit's permanent filter on a hard surface outside and it is ready to go for an other two months. I think you could get about 16-18 cut-outs per sheet at $18 per sheet, it is enough to last 32-36 months (approx 6 dollars a year).

Crystal 50 Humidifier

Works ok I find I am filling it every three weeks & not the couple months it advertise although I have tried other ones & they do not work well.

I use this puck as a adjustment to large humidors. my primary source of humidity is nano beads, and I have one of these gel puck in each box as well. they work for about a year and occasionally discolor, but for 8 bucks & free freight they're not bad. I've found that they need to be recharged ever 3-4 weeks.

Does a great job of keeping the humidity level in my humidor. Doesnt need the special recharging liquid. I use distilled water.

The humidifier has a magnet installed underneath, and includes a circular metal plate with a sticky pad. This allows you to install the humidifier in the lid of your humidor but still easily remove it for refilling.

In my moderate sized humidor (described as 25-40 cigar capacity) this humidifier balanced out at 62% humidity after 48 hours, using distilled water and a digital thermometer/hygrometer. Going on 10 days now and I can clearly see the crystals starting to dry out and separate again. I estimate I will need to fill it again at the 2 week mark as noted in the instructions.

Overall much better than the stock sponge humidifier, well worth the cost.

I had the sponge type and it worked until it started leaking. I was at 72% most of the time according to my Caliber 3 digital hygrometer. I bought this to replace it. Doesn't keep it even above 60%. So I guess these are hit and miss. I even sponged it down one more time after this didn't work, still doesn't work properly. Also this product is not a Madelaine product it is made by IQ which is the same brand as the one that started leaking.
