5.0 out of 5 stars Fantastic Machine, Automatic, Very Quiet, Great looking
Reviewed in the United States on April 23, 2020
** 3-week update **
After a few weeks a clicking noise developed in the fan when running on the sleep (lowest) speed. Looking at the fan it appears there maybe an imbalance that over the weeks developed into a motor shaft tapping. Make sure to inspect your unit for a balanced fan. I just issued a replacement on the 5500-2 so we'll see what happens.

** Original **
I spent weeks comparing units on Amazon and elsewhere. I didn't want to spent > 200 on an overbuilt fan, or be stuck buying overpriced filters. I ended up buying the Winix 5500-2 and Renpho AP002 and first impressions with the two units are that they both appear well built, quiet, and have the automatic mode I really wanted.

TL;DR;
Winix 5300-2 - Quieter w/Smarter hands off Automatic technology & Ionizer - Set and Forget!
Winix 5500-2 - Identical in Black w/Remote & washable carbon filter
Renpho AP001 - Incredible unit, Amazing filters, Low cost ownership!
Renpho AP002 - Almost identical, slightly more air volume

FILTERS
The Renpho filter has a price and feature advantage over the Winix. Both units have H13 Hepa filters, both have the honeycomb active carbon filters (for capturing VOC), and both have a washable pre-filters for catching large particles. The Renpho however has 2 bonus layers, a microbial coating on the Hepa filter, and an additional charcoal filter sitting before the carbon filter to collect larger particles. The Winix does claim the active carbon filter is washable - Renpho does not make this claim, however both appear similar so it maybe purely marketing. The Renpho filter is shorter and fatter - if you ran the numbers they both likely have similar surface area, thought the Winix is CADR rated for 360 sqr/ft while the Renpho is 330 sqr/ft. They are close.

Renpho OEM filters sell for $25 for a full replacement. Winix OEM filters sell for $50 for a full replacement. Renpo claims the filter should be changed every 6 months, Winix claims every 12. I assume this is reflected in their price strategy, however since the filters are so similar, I doubt both claims can be true - and this all depends on how dirty your air is! So cost of ownership is likely less with the Renpho.

AIR IONIZATION
The Winix comes with an Ionizer (called Plasmawave) and Renpho does NOT. The Ionizer charges any particles passing through the unit so they are heavier and will float to the ground and out of air. If you're concerned about Ozone gasses, then this is a feature you can disable and is not a feature on the Renpho.

SOUND
This is a real issue for me - I am sensitive to sound and like the home quiet at night. Deciding on a unit for my children makes this even more important, and I don't want to force them into a white machine for air filtration. In Sleep mode the Winix is significantly more quiet at (advertised) 26dB where the Renpho is at 35dB. With the Winix 10ft from the bed I can just barely hear it. The Renpho is noticable but not "loud". The Winix appears to have 5 speed modes, Sleep, Low, Med, High, and Turbo. The Renpho has just 3 modes, Low, Med, High, with Sleep mode being the Low mode with lights off. Here's the rub however - outside of Sleep mode, the Winix sounds "louder" having a higher pitched whine while the Renpho is more of a hum. If I was going to just set this on High in a corner and forget it, then Renpho is the winner. For a quiet bedroom the Winix appears the winner.

AUTOMATIC MODE
This was a huge feature for me and the Winix is a much "smarter" unit. Both units have a similar Automatic feature, sensing the air, bringing the fan speed up or down according to the readings. Both have light(s) indicating the current air quality reading. The Winix however had a light sensor that, when the unit is in Automatic mode, will place the unit in Sleep mode when the lights go out (for more than 1 min). In the morning the unit goes back into Automatic mode. This is huge if you appreciate how quiet the unit is. You can set the Winix to Automatic mode and not touch it until your next filter cleaning. If you wish to use the Sleep mode on the Renpho you will need to push the Speed button to cycle through the speed options back to Sleep - and then again in the morning cycle back to Auto. In reality you maybe better covering the lights with black tape and leaving it in Auto or just leave it in Sleep mode permanently.

REMOTE
Winix has one, Renpho not - for my needs this is a non-issue.

CHILD LOCK
Renpho has one, Winix does not - this is a great feature if young kids are around!

APPEARANCE
Personally I think the Winix looks clean, modern, and the black color blends well into a corner near furniture. The Renpho AP002 like the Renpho AP001 have their signature funky look which is fine but not as refined. It's an air purifier, so who cares, but it is also a visible piece of equipment in your home.

For us the Winix seems more appropriate for a bedroom, the Renpho for a living room. Winix higher cost of ownership justified by the features and sound levels, Renpho for lower ownership cost.

If the Renpho unit was QUIETER (ahem - hint hint Renpho) then I would just go that route - save on upfront and ownership cost.

SIMILAR MODELS
The Winix 5300-2 and Winix 5500-2 are the exact same physical unit in different colors with different filters. The 5300 is gray, the 5500 is black. Only the 5500 has a remote. The 5500 has their "advanced" AOC Washable Active Carbon filter, while the 5300 has a disposable active carbon. The 5300 Hepa filter is slightly thicker (good) and you get 4 disposable filters with each replacement. If you buy the 5500 and don't like the washable filter it comes with you can buy the 5300 replacement pack and use them instead. For $23 more we went with the Winix 5500-2 to test the AOC filter, and for the black aesthetic. Currently you can get the 5300-2 for $129 (Amazon) and when I purchased the Winix 5500-2 for $152 (now listed at $159 on Amazon).

The Renpho AP001 (often found as RP-AP001 or AP-001) and Renpho AP002 are very similar products, both using the exact same filters, having different aesthetic designs, and with the AP002 having more airflow (for supposedly the same sound levels) and covering 30 sqr/ft more space. The AP001 has a dedicated Sleep button while the AP002 Sleep mode is the first option on the Speed cycle button - more daily button work for you. Currently the AP001 sells for $99 (Renpho direct) while the AP002 for $137 (Amazon). I bought the AP002 thinking the newer model maybe more quiet than advertised. If we get another Renpho it will be the AP001 for $37 bucks less.

I like the air quality first sneezeless night in years.
Studio apartment so unit has to cover at least sleep/living room area 267 sq ft
I like the auto feature / select and unit does the rest. Light dims when lights go out.
Powerful and efficient well made
Easy to clean just remove front panel. Pre filter can be easily removed for cleaning or left in place and vacuumed. Way easier than round purifiers. I had 3 of a well known brand and I didn’t like flipping them upside down to open and remove filter. I also didn’t like rotating the filter to vacuum …very awkward
I like the price of the unit and the filter replacements which are cheap. Reading reviews that said the washable carbon filter made the 5505 noisier so I went with the 5503. I don’t like washable and prefer disposable anyway…,faster. The round brand name unit is expensive and filters expensive to replace.
Winix has Easy to carry handle built into top if it needs to be moved.
I think this model will go into my large bathroom next to the litter box… I have 2 cats. It is a separate room from the rest of the apartment so it needs its own. Winix has a smaller round model which would probably be a more appropriate size but I don’t like the round ones. Then I plan to get the 9800 to replace it to be sure my whole studio is fully circulated. There is the kitchen and hall. It is the same as 5503 with same filters but wider opening on front panel and larger motor/fan and deeper (12”) to accommodate.
I set the 5503 on auto and leave it whether my windows are open or not. Might as well purify air coming on.
9800+5503 for studio probably way overkill but I like that…they will clear the air fast and noiseless. Larger units can run on lower speeds. I am sitting here writing this review with my nose enjoying every breath…. Ahhhhhhhh. It feels so good I just want to sit and breathe

Update 4/27 one week later
As planned got the 9800 for living/sleeping/kitchen in my small studio and moved this one 5503 to large bathroom next to litter box
New pics added showing filters when I first removed front cover. 5503 did nice job of catching fur and litter dust.
Second set of pics show after vacuuming both pre filter and carbon since it is not washable. Area lower right is next to litter box so filtered more. Rotated and replaced
Hepa filter pristine
May have to replace carbon more often
Might get 2 washable and rotate weekly so use one while other dries like I do with my robot vac
Update 4/30
My cats eyes have cleared up. They both used to have a lot of discharge in the corners that I was always cleaning off. They don’t have that anymore since I started using Winix 5503 and 9800.
Update 5/1
Last night my nose was runny so I turned up the 9800 to 3 and my nose cleared up restful night sleep

Update 6/23/24
stayed with replacement carbon filters for both don't like washing, vacuum once month.
5300 doing great in bathroom, gets dust, pet hair. air quality light/fan change with humidity. Carbon filter looks like it will need replacing every 3 months
9800 doing great in living/sleeping/kitchen air quality light changes at times

Reviewed in the United States on November 3, 2024
My family and I love this device. The Winix 5500-2 is a highly rated air purifier known for its effective air cleaning and user-friendly features.

This model is particularly effective in spaces up to 360 square feet, making it ideal for most bedrooms and living rooms. It includes a smart sensor that adjusts fan speeds automatically based on air quality, and it switches to a quiet Sleep Mode in dark rooms, which is especially useful for nighttime operation. Reviews praise the Winix 5500-2 for its impressive particle and odor removal capabilities, noting that it can significantly improve air quality in a short amount of time.

It does produce some noise at higher speeds, but it’s generally quiet in its lower settings, making it unobtrusive in a home setting. Overall, the Winix 5500-2 offers strong performance and reliability for anyone looking to improve their indoor air quality.

4.0 out of 5 stars 5500-2 has no remote.
Reviewed in the United States on October 13, 2024
I ordered the 5500-2 unit to replace my 4yo Winix air purifier. This is unit is identical, possibly the same model, but this newer unit did not include a remote. Fortunately, I still have my old remote that works with the new unit. So far it runs quietly and seems to do a decent job and reducing dust and pet dander in the air. Even without the remote it shouldn’t be a deal breaker because the air purifier doesn’t need much attention until a filter needs to be maintained. I took a star off because the description is misleading, unless the manufacturer or seller wants to start shipping remotes separately.
